Is it time yet?

Everyone sits on a bench with their leg crossed all in the same way.  The first person on the bench asks "is it time yet?" to the person on her left. This continues down the bench until the last person is asked. She responds "no." This message gets relayed up the line. This is repeated a few times until finally the person at the end decides it is time. The message gets passed down the line. Everyone on the bench uncrosses their legs and recrosses them the other way.
