Here's a story I once heard which was supposed to have really happened but I suspect it was a joke that that turned into an urban legend:

During a slow period in a baseball game, the TV cameras would sometimes focus on interesting people in the stands.

One time the camera caught, and lingered on, a couple who were getting rather romantic.

The announcers, watching on their monitors, couldn't resist commenting.

One of them said, "Hey, looks like those guys have an interesting game going on."

The other ad-libbed: "Yeah, he kisses her on the strikes, and she kisses him on the balls."

Supposedly, when they realized what had been said, they both convulsed with laughter and were unable to talk for several minutes.
