Nafets
A guy who drinks diet Coke like it's water and acts like a complete idiot. He's smart, but you'd never guess it from his dumb chipmunk impressions and his terrible prank calls.
He called my phone at 3 a. m. and pretended to be a chipmunk. I yelled at him for an hour.
He did a prank call to my dad's boss. It was embarrassing, and my dad got fired.
He once rode a bike for 10 miles just to prove he could. He didn't even stop for snacks.
