Seen on an electrician's truck: Let us remove your shorts.
======================
A woman saw an electrician walking up her drive. She rushed to the door. "Why have you come today?" she barked. "You were supposed to repair the doorbell yesterday."
"Yes, I know," said the electrician. "I rang three times but there was no answer, so I thought you must be out."
======================
When a pipe burst in a doctor's house, he was forced to call the plumber. The plumber came over, fiddled around for half an hour and presented the doctor with a bill for $600.
"600 dollars for a half an hour's work? This is ridiculous! I don't even make that much as a doctor!"
The plumber replied, "Neither did I when I was a doctor."
