I'm going to lead with my strong suit: I make more corny jokes per second then 98% of people and more half decent jokes then 14% of people. Boom. Sorry about that crater in the floor, you'll be able to walk again in a couple hours.
I'm a very, very confident individual. Some might feel tempted to use big, mean words about that like "arrogant twat" (Even OKC, apparently), but that implies that I can't do all the things I say I can, which is ridiculous. (That was a joke. Mostly.)
Besides, would that awkward 'smile' lie to you?
For a medical school app, I had to put three words a college roommate would use to describe me. I asked and his choices were amiable, astute, and helpful. Take that for what you will.
