After a ferocious hail storm, the blonde drove her very dented BMW to the garage to get fixed, the mechanic told her he was to busy today with all the repairs, due to the hailstorm, and if she could come back next week,
The blonde answered, Oh no that is way to long, can't you do something quick?
The Mechanic eyeing the blonde smiled and said, I tell you what, here a secret, if you drive your car home, and tomorrow morning early you get up, go to the back of your car blow into the tail pipe, and all the dents will pop out, okay?

The next morning the blonde hunkers down and is blowing with all her might in to the tail pipe, nothing happens ... but a blonde friend of hers walked past, looked at her red face and asks what your doing?

The first blonde explains, the second blonde starts laughing, and says geez your stupid, that will never work!
You have to roll up the windows first !!
