Its a busy Saturday at the barbershop, and this guy walks in, asks the barber "What's the wait time?"

Barber says "About an hour and a half." Guy walks out.

Next Saturday its a little busy but not as much as last week, same guy comes in and asks the same question.

Barber says "About an hour." Guy walks out.

Next Saturday, same gay walks in, same question.

Barber says "About an hour and a half." Guy walks out.

Barber says to his friend how happens to be hanging out in the barbershop "That guy's been in here three Saturdays in a row. Always asks how long the wait is and never comes back. Will you follow him for me and see what he does?"

Friend says OK, and comes back a while later. Barber says "Well, where did he go?"

Friend says "You really don't want to know."

Barber says "Come on, tell me. Where did he go?"

Friend says "Well, he went over to your house and your wife met him at the door wearing lingerie. They kissed and went in, and I watched the light go out in your bedroom."
