Blond tailpipe
 

Tiffany (a blond) decides to visit her friend Tammy (also a blond).
When she gets to Tammy's house she finds Tammy blowing in to the tailpipe of her car.

"Tammy, why are you blowing in to the tailpipe of your car" Tiffany asks.

Tammy replies "I have a dent in the side of the car and the mechanic told me I can pop the dent out by blowing in to the tailpipe".

Tiffany rolls her eyes and laughs at her friend "Tammy, you're such a blond! It will never work.....

the windows are down".

Hahahaha. That's excellent.

Love it.

On the one hand, lol.

On the other I feel as if I'm missing half the joke: why would a mechanic say that?

Take out the word "in" from what the mechanic said, and in lieu of payment she can get the dent fixed by.......

I see >.>

Either I'm slow or it could be worded better.

Still funny xD
