I don’t drive. Never learned how. I’m 25 year old male and I don’t know a thing about cars. Maybe someday I’ll get my driver’s licence…but as for now, it’s all greek to me.
I can’t draw graphic depictions of male genetalia on white boards. At least evryone in my dorm can.
I can’t whistle. I’ve tried to learn, but it’s just not possible for me. Of course, I didn’t learn how to blow a bubble until I was about 15, so maybe there is still hope. :rolleyes:
I can’t ride a bike. I just never learned. I’m 21 and I’ve never ridden a bicycle without training wheels in my life.
Blow up and tie balloons. Terrified they’ll blow up in my face and my fingers are too big to tie 'em.
I also can’t whistle. I’m the only one in my family who can’t. I can belch pretty damn well though.
Yeah, that’s my moms. She is TERRIFIED of balloons. We, of course, make sure that they are as close to her as possible while we are blowing them up though. 
Blow bubbles (no Michael Jackson jokes, please).
Go ahead, offer to teach me. You’ll wind up with a wad of bubble gum accidentally spat into your face, just like all the others.
I cannot roll my tongue. Although I hear this is genetic, so it’s not my fault.
Hal, it’s all that oral sex your giving to the missus.
Same here! Never learned. It was a big deal when I was a kid. Now, not so much.
I’m pretty awesomely good at remembering movie trivia (but there are plenty who are better) and I’m fairly decent at drawing stuff from my imagination (but once again, not the only one, plenty are better).
I can’t snap my fingers.
arithmatic in my head. Seriously. Even the most simple 2 digit addition…gotta write it down. Drives my geeky-math-nerd husband bonkers.
I can’t open my eyes under water. I’ve tried many times, but I simply can’t bear the feeling of water in my eyes.
I don’t drive or know anything about cars, either. (We just saved a bunch on car insurance, without any lizards being involved!)
I don’t know how to whistle with two fingers in my mouth. (My mom did this, and you could hear her for blocks.)
Or do math in my head. I have to use a calculator.
I can’t write cursive. I learned how, and I could probably train myself to do it again, but I can’t even write my signature legibly in cursive- I always write in very neat uppercase letters, but no cursive…
I also can’t whistle with two fingers, open my eyes underwater, or roll my tongue, but I can build (and drive!) a car, ride a bike, and blow bubbles. I usually wind up in a tabloid after trying all that though, so I have given up 
I can’t cross my eyes.
And it’s not just that I can’t do it on purpose–they don’t cross even when i try to focus on somebody’s finger placed on my nose, moving towards my nose, etc. (My friends did a bit of experimenting when they first discovered this.)
It appears to be genetic, since neither my mother nor my sister can do it, either.
Can’t get a date. :rolleyes:
23 and never have figured it out.
I cannot currently eat or drink. At all. If I try, my pancreas gets all pissy and it feels like I’m being stabbed in the stomach for a few days. I haven’t had solid food in two months. I’m living off liquid stuff pumped into a tube hanging out of my stomach.
I win.
Okay, Smeghead wins. That really sucks!
But in the interest of keeping the thread going: I can’t smell. (That’s not to say that I don’t smell). I had an operation when I was around 4 years old to stop frequent nosebleeds, and since then I’ve had no sense of smell.
Good for riding the bus and walking through the Tenderloin or the Haight. Bad for being able to tell if my milk’s gone bad, if I’ve got B.O., just how bad smoking makes my breath stinks, or buying bath soaps and perfume and such as gifts.
