Low Brainpower

A blonde woman, driving a Porsche, she sees another blonde with a Porsche that has broken down on the side of the road. She stops to ask whats wrong. The owner of the broken Porsche says, I just had a look under the hood, and I think that while I was driving, somebody stole the engine.


Oh, dont worry, says the good Samaritan. I have a spare one in the back of my Porsche.
