My professor was trying to gauge where everyone was at by asking us to work in groups to do a few simple problems. One of the examples he had us do was to figure out how many seconds were in a day, a month and a year, expressed in scientific notation. This one guy, though, spoke up and said, "Actually, I got ____ because instead of using the answer from the # of months multiplied by twelve months, I took the answer from seconds in a day and multiplied by 365.25 to account for leap year." After a few seconds of silence, I said quietly, "Smart ass. Someone slap him." and this black chick sitting behind him slapped him lightly in the back of the head. I cracked up and even apologized to him after class and explained that I was joking. It turned out he knew the girl who was sitting next to him, which lessens the randomness, but it had me laughing my ass off.
