Dent Repair  

A blonde got a dent in her car and took it in to the repair

shop. The repairman, noticing that the woman was a blonde,

decided to have a wee bit of fun.

So he told her all she had to was take it home and blow in

the tailpipe until the dent popped itself out.

After 15 minutes of this, the blonde's blonde friend came

over and asked what she was doing.

"I'm trying to pop out this dent, but it's not really working."

"Duh. You have to roll up the windows first!"
