This joke has a little history behind it.

Back in the 1960s in Chicago there was a radio station (WLS?) with a
very popular disk jockey named Dick Biondi who told this joke on the air
and got fired for it the very same day.

A newlywed couple who were both avid baseball fans attended a game at
Sox park. They were still on their honeymoon and very affectionate, hugging
and kissing so much that they werent able to follow the game.
After a couple of seconds of thought the wife says, Ive got an idea,
honey. You kiss me on the strikes and Ill kiss you on the balls.
