Three math grad students meet for lunch. One rides up on a new bike.
The first two say “Hey, cool bike, where’d you get it?”
The third says I was tutoring this girl all semester, and earlier today she came over and said that because of my help she passed the class, so she wanted to thank me. Then she took off all her clothes, got on my bed, and told me I could have anything I wanted.”
The first math grad says “You made a good choice taking the bike, you would have looked funny in girl’s clothes.”
The second says “Yeah, and they probably wouldn’t have fit anyway.”
