I can’t whistle, roll my tongue, and I used not to be able to snap my fingers.
Can some people really not do the vulcan \V thing? It feels unnatural with my left hand, but both hands do it fine.
Shade: Mrs. CaptMurdock can’t do the Vulcan peace sign. She is amazed that I can, with either hand (and so can our teenager, Kid CaptMurdock). Of course, she humiliates me by demonstrating how well she can whistle (I can’t).
I think I have the mutant power known as “Tijuana Knuckles.” 
I can “crack” my knuckles on both hands simultaneously by making tight fists.
I can -
- wiggle my nose ala Bewitched
- curl my tongue
- flare my nostrils
- wink with both eyes
- lift one eyebrow
- snap my fingers on both hands
- pop my jaws in and out
- do the Vulcan “Live long and Prosper”
- cross both eyes and make them “shiver” while doing it
- curl my lip to the right side
-whistle regularly
Can’t
-finger whistle or that other curl your tongue whistle
Can do:
- I can curl my tongue
- I can wiggle my ears a significant amount
- I can do the one-raised-eyebrow thing
- I can crack all of the traditional joints
- I can cross a single eye (my right eye)
Can’t do:
- Roll my r’s as in Spanish. Wish I could.
- Bend any joints in funny ways.
- Dislocate anything voluntarily (I don’t even want to try!)
- Whistle with my fingers. Boy how I wanted to do this as a child.
Here’s an odd one that isn’t too challenging, but seems to be culteral:
My wife and her family are from Brazil, and they frequently do this thing similar to finger snapping: they press their thumb against their middle and ring fingers, leave their index finger loose, and then flip their arm up and down in such a way that the free index finger slaps against the middle finger, making a muted finger-snap sound.
They were impressed when I was able to do this – apparently no gringos can. I didn’t tell them that when I was younger and partook of chewing tobacco, this was the exact motion one used to pack a tin of snuff.
I can’t do the Vulcan thing, touch my tongue to my nose, wiggle my ears, raise one eyebrow, or whistle with my fingers.
I am, however, double-jointed, most notably in my hands. That’s the moving the top finger joint/having fingers that move way the heck back without breaking thing. It’s totally natural to me, but it REALLY freaks other people out; I can bend them far enough back to touch the back of my arm/wrist.
I also can cross my eyes, curl my tongue, snap, whistle normally, and curl my lip ONLY to my left side.
Oh–I’m also extremely flexible. I’ve never had an itch I can’t reach, and I don’t get hurt NEARLY as much as I should given my klutziness, 'cause I can wriggle out of stuff. This is why I don’t understand when someone says, “can you scratch my back?”
My high school girlfriend could do that. So cool!
I am so jealous.
I can:
-Roll my tongue.
-Wink either eye.
-Whistle a tune.
-Whistle with two fingers in my mouth, but only intermittently. Half the time I just wind up with spit on my fingers.
-Make the Vulcan sign. I can also make the inverted-Vulcan sign: two middle fingers together, pinky & index apart. \ || /. Try doing that on your right hand, while you do Vulcan \ // on your left, then alternate.
I can’t:
Dislocate anything.
Crack my knuckles.
Wiggle my ears.
Raise one eyebrow.
Wiggle any toes independently.
I can:
Whistle with fingers and without (drives my husband nuts)
Cross my eyes
Cross one eye at a time while the other looks straight
Wiggle my ears (hubby can’t do that either and our 6 yr old can now–hee hee!)
Crack my knuckles
Raise either eyebrow
Flare nostrils
Curl either side of my lips
Roll my tongue
Make the Vulcan sign with either hand
But the one that my family used to call on whenever things got boring is:
I can walk on my toes with them curled under–said activity has been curtailed a bit since developing arthritis in toe joints–gee whiz, go figure!
I can not pop my neck or dislocate/double joint anything…wish I could!
There are some truly talented people here!!
I can’t snap my fingers either. No one in my family can. It may be genetic.
For those of you interested in making the Vulcan hand sign, you may be able to learn to do it through practice. I couldn’t do it as a kid, but after devoting some of my long, boring bus rides home from elementary school to working on it I finally mastered it and have been able to do it ever since. Try holding your middle and ring fingers apart with the other hand until you get used to it and can do it on your own.
I’m another one of those strange people who can’t snap their fingers . . . but only my right hand.
And I can’t whistle or wink.
but i CAN cross my toes.
its a great party trick in the summer
Oh, another thing I can do.
One day at my grandma’s house, she gave me a book of the magic-eye stereograms. I spent two hours looking at them and figuring each one out.
Now, when given one, I can see it in seconds. My eyes kind of cross at exactly the right angle to see it perfectly. My favorite trick!
Theres not a lot I can’t do…
As for cans:
Pop both thumbs out of their sockets,
Shimmy my eyes,
cock one eyebrow at a time, or both at the same time,
crack knuckles in any way I want,
Bend my elbow the other way a bit (its not a lot but still enough to freak out people)
Twist my arm 360 degrees (the real way not the cheap magic trick way)
Bend my leg behind me so my toes point straight up,
Pop out my back blades,
Hmmm, thats all I can remember but I know that there is more…
I cannot:
Whistle using my fingers (haven’t tried to whistle using my toes, maybe I will try that after my next shower… see below)
Vulcan Live Long and prosperfinger spread
wiggle my ears
while sitting cannot cross my legs so that my shins are parallel (always told it was girl style even but I wanted to avoid sexest stereotypes)
I can:
Touch my elbows together in front of my chest
Touch my elbows behind my back
Literally can stick either foot in my mouth (if it would fit, the toes do)
Touch my feet in back of my head
(despite being approximately 60 lbs overweight)
roll my tongue like a “U”
Fold my tongue like a piece of paper
whistle very loudly without use of fingers

Correction: I just tried this for the first time in several years, just to verify, and it turns out I have lost the ability to touch my nose with my tongue. 
i can do the old “rub belly with one hand, tap my head with the other” (or vice versa)… wow
jsc1953, I can do the Vulcan thing and inverted Vulcan sign, opening and closing, at the same time, and which hand one is on does’t matter (though it is easier with the true Vulcan thing on the left). I’ve never met anybody else who could do this easily.
I can’t:
whistle (any way)
bend my joints in any sort of strange way
I am by no means flexible
dislocate my joints
touch my nose with my tongue
make my eyes ‘shiver’
I can:
crack just about every joint in my body that moves
cross my eyes
raise one eyebrow (right)
curl my tongue into a U
wiggle my ears (and my right one can wiggle separately)
flare my nostrils
wink (either eye)
Ack! I swear, your post was not here when I posted, Cervaise!
I can’t whistle at all, in any way. Always been very embarassed by that. I also can’t run more than a few feet without an ankle giving way. Oh, and I can’t snap my finger either.
One thing I can do which seems to amaze other guys is to sit in a lotus position. (And no, I have never ever done yoga.) I normally sit with one foot crossed under the other leg anyway. My knee is flush with the chair/floor/whatever. With most guys I’ve seen try it, their knees end up at about 45 degrees from the floor. I have no idea why.
Without using my hands, I can cross my little toe over the toe next to it…both feet.
