A blonde woman is driving a Porsche. She sees another blonde woman with a Porsche that has broken down on the side of the road. She stops to ask what's wrong.

The owner of the broken Porsche said, 'I just had a look under the hood, well, while I was driving somebody had stolen the engine.'

The other said, 'Oh, don't wory, I have a spare one in the back of my Porsche.
