This guy Curt gets a call from his buddy John one day, and John is on the phone crying.

Curt asks, "John, what's wrong? You sound really upset."

"Well," replies John, "my wife's been cheatin' on me."

"With who?" asks Curt.

"The neighbour," replies John.

"That damn dirty slut!" says Curt.

"Yeah," replies John, "you think I'm upset, you should've heard how upset the neighbour's husband was."
