Like MissTake, I can do most of that stuff with my hands, too. I used to be able to bend my thumbs backwards to touch my wrist, but I’ve lost that flexibility as I’ve gotten older. I can still bend them forward to touch the inside of my wrist. My knees hyperextend and bend backwards. My father could do this too, so I must have inherited that from him.
I have mismatched second toes. The toe beside the big toe on my left foot is noticably smaller than the same toe on my right foot.
Ha! I have up to 12 hairs growing out of the same follicle. Several sets, on my chin and jaw. They look like one huge fat hair, almost like horns (Darth Maul anyone?), but when I twirl them, they separate.
Yeah that makes sense. I remember the doc telling me that I was “allowed” more curvature in my back because of the extra vertebrae.
I get some that have so many tiny white hairs that if I pluck it, it looks like goose down.
I can also touch my nose with my tongue.
Hmm, hard to beat some of these. My biggest body weirdness is my skin. It’s incredibly pale and prone to endless irritation. When I was a kid I was asked all the time whether I was albino (should be obvious I’m not given my eyes are grey, but kids don’t necessarily know about the red eye thing.) I’m allergic to the sun (UVA), most laundry detergents and many bar soaps and have dealt with teenage acne, two kinds of eczema and psoriasis. I can’t wear any metal rings unless they are white gold - no silver or copper or anything with nickel or I break out. The only kind of watch I can wear must be backed with stainless steel.
Sr. Olives also has a weirdness about his skin - when you touch it, it turns red and stays that way for several minutes. He’s kind of like those t-shirts they sold in the 80s that changed color when you applied heat to them. If you press your finger lightly on his back and draw an imaginary circle, in about 30 seconds there will be a big red circle on his back, and it will stay that way for several minutes. If you grab his arm, there will be a giant red handprint there. Weird.
My SO has that, and was told by a former girlfriend who was in med school that it was a mild form of Pectus Excavatum.
Mine, too, apparently, since all my sunglasses have to be slightly bent to look straight on my face. Needless to say, I buy cheap sunglasses so that if they break during the bending process, I’m not out a bunch of money.
I wonder if that’s what I have on the outside of my right ankle. A large bump appeared there one day, almost two decades ago, and never went away. My mother has one in the exact same location.
My second toes are the same length as my big toes, no more and no less.
Mine are about the single kernal size. I have a friend who has NO toenails on her little toes, and has to paint fake ones on when she gets a pedicure.
Dermographia? I dated a guy in college who had that, and we’d write slogans on his arms before political rallies.
I have such a small mouth that as a child I had to have four permanent teeth cut out of my gums prior to their arrival, as there was no room in my jaw for them. I have only 24 teeth in my head currently.
When I had my wisdom teeth removed, the roots were so unformed that it took the dentist 20 minutes to remove all four. I had no swelling and little pain, and went out clubbing that same night.
I have a pointy bony bump on the back of my skull just above my spine, as if my skull had been shaped in clay and that particular spot was where the artist snapped off the rest of the clay. It points down toward my spine. I like to think of it as the place where my body was connected to the Matrix 
I have this also. I didn’t know it was odd until a doctor giving me a physical told me about it. He asked me if I knew my skin had this characteristic (of course I did) and he drew an “X” on my chest. The “X” appeared like one of those old poloroids and it will stay for a few minutes or more.
Thanks for making me feel like a weirdo, Doc!
I can’t remember the name of the condition, but apparently it’s pretty rare. Tell your hubby there’s at least one more of us out here! Up until your post, I’ve never seen anyone else have it or heard it discussed so I’ve never mentioned it.
I’ve been told by technicians at the shops where I get my glasses that this is true of almost everybody, to some degree. I certainly have to get new glasses adjusted so they don’t sit crooked on my face. I’m not sure if the asymmetry that causes this is in my nose or my ears, though.
ETA: Physical asymmetry is usually a result of stress at some point while you were growing, which, strictly speaking, means it’s not a mutation.
Same here for all of this, except I can do it with both shoulders, made a guy puke once demonstrating. Except I’m not sure its a true or full dislocation in my case. I do this strictly through muscular control not manual manipulation. Looks disgusting and cool though if your not expecting to see it:D
I have some hypermobility in my upper torso. I can’t dislocate my shoulders at will, but I can “pop” them endlessly and make my clavicle stand out on both sides. I can hyperextend my elbows, fingers and ankles somewhat, more on the left side than the right.
I can control my abdominal muscles in a way I’ve never seen anyone else do; basically I can shift my belly from side to side without moving my hips or shoulders. I can even move my navel in circular and figure-8 motions. Is there a name for that?
In belly dance, we call it isolations. And I hate you a little bit for being able to do it so easily. 
Yup, good ol’ pectus excavatum:
http://en.wikipedia.org/wiki/Pectus_excavatum
I am not the model on the wiki page, but his “extreme” case seems to be quite comparable to mine.
Yes. To both. My ring finger gets my pens, while my pinky and thumb do all the snapping.
“Belly-dancing”. 
ETA: Bah. Longest ninja ever. That’ll teach me to leave a post sitting in preview too long.
My wisdom teeth came in, and because I have a HUUUUGE head (long jaws) they came in straight and normal, like their molar-y brethren; but one of them has no crown. Instead of a sorta-flat mashing surface with 5 mild points and a central depression, I have one molar that looks like I mugged a toothed whale and implanted what came out of its mouth: a single conical spike.
X-rays confirm it: perfectly normal root structure, and then, above the gumline, WHALE TOOTH. (Albeit scaled to a mostly-normal human jaw)
At least it’s easy to keep clean, since its “sides” are well away from the adjacent tooth.
Dental anomalies seem pretty common-- Me, I’m missing the second bicuspid on the lower right side. The baby tooth fell out, but there was never any adult tooth to replace it. Between that and the braces I had as a teenager, everything on the lower jaw is in funny places now: I had room for one wisdom tooth on that side, and my lower incisors are all shifted a half a tooth over.
I have a small, rounded mole on the left side of my nose. One of my uncles does, too, as did my grandfather, all in exactly the same place.
And everyone in my extended family has toenails that grow straight up, rather than forward, on our little toes.
I’ve got this too in a couple of places on me.
Glad to know I’m not the only one !
Club feet. Very flat feet. Second toes noticeably shorter than the big toes. Toes # 2 and 3 on both feet webbed. Only two wisdom teeth; both were uppers and came in sideways. The shape of my face is definitely asymmetrical. Inherited my mother’s hefty thighs and my father’s spindly shins/calves. Ring fingers are slightly longer than index fingers. Left eye is slightly color blind (red). Can “roll” my tongue. Photic sneeze (sunlight only). Port wine stain on the back of my head. Not a mutation, but definitely different: Most people my age have gone completely gray but I have only a few gray hairs, (Both my parents kept their hair color well into their sixties/seventies, going gray very slowly.)
My wisdom teeth came in at age 12. My hair began to gray at age 13. I have scoliosis, a slightly clubbed foot (corrections made) and an unusual sensitivity to sunlight. Other than that I’m right as rain - except for all the other stuff… 
My beard is reddish. My mustache is blond. All the other hair on my body is dark brown.
I have slight Morton’s toe, but it’s hard to tell, since there’s about a 3/4" gap between my big toe and second toe on each foot.
My eyes shift from blue-green to brown-green on a regular two-month cycle.
I have Arachnodactyly, which was hilarious to discover, since I was called “Spider Fingers” in high school.
Oh, and I’m slightly color-blind, which I use as an excuse to wear brightly clashing clothes.
WTF!? :eek: Mother of God! As in… completely, excised?! :dubious:
I’m going to go ahead and assume, (or at least, hope!) that you no longer have sex with the individual that perpetrated this heinous act.
“Webbed” toes… The split between my index and middle toe is considerably shorter than what I’ve observed of other peoples toes. Oddly enough, I’ve been complimented on having “pretty feet”, on more than a couple of occasions.
