Double Bumper

A man put his car in reverse and accidentally drove it into a wall. He
took it to his mechanic, who replaced the dented bumper.

A few days later, he actually did it again. "I'm so embarrassed," he
moaned to his wife while he reached for the phone.

"Why not tell him it was me this time?" his wife suggested.

"I could," he said while dialing, "but that's what I told him last
time."
