same school

As an engineer in an upmarket hotel, I was once asked to repair or replace the television in a guest's room. When I arrived, the couple was watching a picture one-third the size of the screen. As all our spare sets were in use, I figure what he heck and struck the side of the tv with the heel of my hand. The picture returned to full size.

"Look honey," said the wife to her husband. "He went to the same repair school as you!"
