A guy comes in, wearing an orange t-shirt and what looks like shorts or something (I am not a very observant person)
Guy: Are you a librarian?
Guy: My Halloween costume is crossdressing. Is that okay?
I look at him more carefully and realize he is actually wearing a very short denim miniskirt. He is holding onto the hem of the skirt in front and back as if he's afraid it will ride up.
Guy: Don't worry, I won't expose myself. I'm very careful.
Guy: Do you know of any costume contests I could enter and win?
