I'm a school bus driver and whenever I drop off sports teams I always tell the kids "have a good game". About a third of them respond with "thanks, you too". I like to imagine them dropping the winning touchdown pass because the fact that they said that to the bus driver is rattling around their brains.

Sometimes I also say "make your enemies cry" and they say "thanks, you too" to that as well. At least that one makes some sense to a bus driver.
