If You Need Anything

I was just watching a fragment of Demetri Martin on Youtube. If you watch the Daily Show you may know him. The video is entertaining, but there was one joke that I really liked:

I went to a clothing store. There was a girl there, helping me. I picked some clothes and she pointed me to the dressing room. She said, “if you need anything, my name is Jill.” “That’s amazing”, I thought, “I never met a girl with a conditional identity before. What if I don’t need help?” “Then it’s Eugene.”
