"One Chickadee"

There was a bird shelter in Britain, where people would look at many different birds. The bird shelter had a sign near it, saying, "One Chickadee". It meant only one chickadee was in the shelter, but people understood it way differently. Usually, a man would get naked, and a woman would suck on his dick. You see... people thought the sign meant, "one chick a D" This bird shelter had to be closed for "constant sexual activity".
