Nerdy little 4' tall student: I'm don't really want to get all tatted up, I mean, nothing ridiculous or anything.  I'm just going to get a sleeve on both arms.
Me: I hope your future job is either really laid back with their dress code, or you don't mind wearing long sleeves every day.
Student: Oh yeah, no problem.  NFL.
Me: Ahhh...and what's your back up plan if that doesn't pan out?
Student: NBA.
