The Obligatory blonde joke

Here's the obligatory blonde joke...

There were two blondes and they had just come out from shopping in a store. They got out to the car and realized that the blonde that owned the mustang had locked her keys in the car. She was trying to pick the lock when she stopped to rest for a second. When she sat down, her friend said anxiously, "Hurry up--it's starting to rain and the top is down!"
