Never heard that one!
I have some good ones... I'm just not sure if I can tell them in English... I'll try though... no wait, I'll look for it on the internet.
This will have to do for the moment:
Britney Spears had just bought her new car and decided to go shopping with her friend and rival, Christina Aguilera. A few hours later she came out and realizes she had locked her keys in the car, so they spent a few hours pacing around the car trying to figure out what to do.
Finally, Britney looked off into the distance and saw storm cloud. She turned to her friend and said," Quick, think of something because a storm is coming and I left the top open!"
