A Newfie suspects that his wife is cheating on him, so he hires a private investigator to monitor her comings and goings.
One afternoon the Newfie receives a telephone call from the P I at his favorite tavern, and is informed that the Newfie's wife and an unknown man are currently in the bedroom at the Newfie's home.
After finishing his beer, the Newfie meets up with the P I at home, and they brew a pot of tea in the kitchen, while planning strategy.
The P I says "OK, what about that guy upstairs?".
The Newfie says "To hell with him. He can make his own fucking tea!".
