Six guys walk into a restaurant and are seated at a table. The leader goes over to the manager and says, "These people are patients from the Walker County Institution. This is our weekly outing. They will probably pay you with bottle caps. Accept the bottle caps. This is
okay. It's part of a recovery program. When they go back to the bus, I will settle with you for what they eat."
The manager agrees to go along with this, so they all order and eat.
They pay for their dinner with bottle caps and get back onto the bus. As the leader walks over to the cash register, the manager tells him, "The bill is $96.24."
The leader asks, "Do you have change for a hubcap?"
