Baseball
A girl goes to a baseball game with a guy she met recently, and he is amazed at her knowledge of the game.
"How do you know so much about baseball?" he asks. "Most girls don't follow it as much as guys do."
"Oh, I used to play in college...before I had the sex-change operation!"
"Uh....I see....." In an effort to keep the conversation moving, he said, "That must have hurt when they ....cut off....your...penis!"
"No, it didn't hurt nearly as much as I thought it would." she replied." What really hurt was when I came back to work and they cut my salary in half."
