Yeah, they call the game "Telephone" because of how those used to work, when they were first invented. Because they were all kind of shitty.

The idea of the game is, everyone stands in a line, and the first person makes up a sentence, like "Mark has chicken pox", and whispers it in the second person's ear. Then they whisper what they heard into the next person's ear, and so on. By the time it gets to the end, usually someone somewhere couldn't hear for shit, and the last person ends up with something like "Mars has chicks with cocks".
