Knock off early

[Claw Hama]

Paddy a carpenter, Tim an electrician, and Tom a plumber working on a job together noticed that the foreman always left on Tuesdays and Thursdays a couple hours early. Since he never came back to the job site they decided on the next Tuesday to leave as well a few minutes after the foreman had departed. Tim headed for the golf course, Tom decided to take in a movie, Paddy decided just to go home and relax. When he entered his house he heard noises coming from the master bedroom, quietly opening the door he was shocked to see the foreman in bed with his wife, he backed away and left the house.
During the first coffee break on the next Thursday the other two guys asked Paddy if he was into leaving early again.
"No way," he exclaimed," Last time I almost got caught."
