Tell us something odd but inconsequential about yourself. I’ll start:
I can’t whistle.
My high school really did burn down in a huge blaze of glory my senior year. The blaze was so quick and bright that it woke me and my mother up in the middle of the night 5 miles away and we drove to see what it was. Gulf War One was just about to begin and we were convinced that Iraq had decided to blow up our tiny Southern town. The only building left was the gym so that packed 400 students into it for the rest of the year with no matching sets of books. They just let us outside all day when the weather was nice. Arson.
I have unusually long arms. I’m about 73 inches tall, but my finger-to-finger arm span is almost 80 inches.
I can write music but can’t read it.
I’m the only member of my family who can’t roll his tongue and doesn’t have a ring around his eyes.
Last year on the same day, my 39th birthday at that, I learned that 1) I’m narcoleptic and 2) I have an African-American ancestor. My entire life I had thought I was just a lazy white guy but it turns out I’m a narcoleptic Negro who can’t roll his tongue.
I’m tongue-tied. So is my son.
I enjoy eating raw lemons with salt occasionally.
My hair is either very dark blond or light brown, depending on who you ask, but I have natural (very) blond highlights in my eyebrows, and a patch of white hair in my beard (which is normally red.)
Noodle that one.
My … uniqueness manifested itself at a fairly young age. When I was 5, I liked getting fed spoonfuls of cod liver oil. I also liked raw carrots. Dipped in mustard. I didn’t like soda.
Also, when I was about 8 or 9, we weren’t well off financially so we couldn’t afford much. So for some of those things that I wanted but we couldn’t afford, I’d make in effigy out of cardboard and watercolours.
I’m hemidextrous (?). I write, sew, use eating utensils, and fence left-handed.
I knit, crochet, mouse, play racquet sports, and use a paring knife with my right hand (although if I’m chopping, I use the left hand.)
I can bat right and left. When I put on eyeliner, I do the left eye with my left hand and the right eye with my right.
I can dislocate my little toe on each foot, and then pop it back no problem.
I like eating frozen Ore-Ida French fries while they are still frozen. As a child, I would pretend my cough was worse than it really was, in hopes of getting the yellow Triaminic cough syrup. And yet as a teen, I had to teach myself to like pizza.
I was once so good at picking fleas off my cats that I developed extremely sensitive fingertips and could kill them (the fleas) even in the dark.
I have beautiful hands. They’re my best feature. I considered becoming a hand model for a while. Now that I’m older, my knuckles are starting to swell with osteo-arthritis. It’s kind of sad to see them starting to become mishapen.
I have an extra cervical vertebra, but my neck doesn’t appear exceptionally long.
My left canine grew in way too late and consequently got pushed behind my left incisor. So now it’s nestled behind the rest of my teeth, where you can’t see it. I considered pulling it out but now I’m pretty used to it. Plus I leave cool bite marks on my apples.
I was born with the joints in some of my smaller toes fused on the ends (no bend). Let’s see, smallest toe on the left and last two toes on the right. I also have extremely small toenails - my smallest toe toenails are about an 1/8th of an inch long when I cut 'em right down.
I eat sour foods like other people eat hot foods - I’ve never met a food too sour for me. The sourer the better. 
I have two webbed toes on each of my feet. I used to be self-conscious about them, but I don’t care anymore.
I have a roommate who likes to dip his Doritos in milk before eating them. 
I like bananas when they’re still slightly green… they’re slightly chewier, and firm, and big, and full, and…
In fact, I’m gonna eat such a marvelous banana right now.
Why are you looking at me like that?
You know how your fingers have two lines on them? One at the tip of the finger and one at the knuckle. My right pinkie has three. I seem to have an extra bone somewhere. But only on the right.
That’s the most inconsequental thing I can think of.
I have arthritis in both my feet and tendonitis is both wrists. I also can’t snap my fingers. Oh, and I can also pop my right ankle quite loudly at will.
