I heard this one from a friend who said it happened to his roommate. I have no reason to doubt it.
The guy and a girl decide to go to a ball game for one date. They look for a nice quiet section of the stadium so they could talk and watch the game and end up sitting on a bleacher about one foot away from each other.
During the game the home team mascot sits down between them and puts one of his arms around each one of them. To their horror they looked up and saw their picture with the mascot wrapped around them being shown on the giant screen.
(They did marry each other.)
