Pat and Mick were sworn enemies, and the slightest wrong word was sure to set them off. As luck would have it, they both ended up at the local barbershop at the same time. 
As they sat there, each being worked on by a different barber, not a word was spoken. The barbers were even afraid to start any conversation, worried Pat and Mick would wreck the place.
When the barber working on Pat finished his shave, he reached for the aftershave.
Pat said, “No aftershave — my wife will smell it and think I’ve been inside a brothel.”
The other barber turned to Mick and asked, “How about you, Mick? Do you want aftershave?”
“Sure, go ahead,” said Mick.
“My wife doesn’t know what the inside of a brothel smells like.”
