I had a classmate in one of my subjs in college who is so vain. He's a looker, looks a lot like Justin Timberlake..
Anyway, I was surprised when he asked me one day, "So do you think I have a nice ass?"
Shocked, I laughed and said, "Yeah bro, I'd tap that anytime" and walked off.
Maybe he noticed I was checking him out most of the time! I never heard from the guy since.
