A younger and older man accidentally bump into each other in the locker room. The older man's towel falls and the younger man hides his eyes when he thinks he'll see the older man's privates but instead they're both wearing the same shorts.
They both smile and as they walk away, the older man slaps the younger man's butt. He smiles rather than having a negative response to the attention.
Later, in the parking lot, they discover that they also drive the exact make color of car. Both want the other to drive on first, but no one moves because they're both too courteous.
