Nog even over die kikker van hiernaast:

A smart girl was crossing a road one day when a frog called out to her and said, "If you kiss me, I'll turn into a handsome prince".

She bent over, picked up the frog and put it in her pocket. The frog spoke up again and said "If you kiss me and turn me back into a handsome prince, I will stay with you for one week."
Smart Girl took the frog out of her pocket, smiled at it and returned it to the pocket.

The frog then cried out, "If you kiss me and turn me back into a prince, I'll stay with you and do ANYTHING you want."
Again Smart Girl took the frog out, smiled at it and put it back into her pocket.

Finally, the frog asked, "What is the matter? I've told you I'm a prince, that I'll stay with you for a week and do anything you want. Why won't you kiss me?"
Smart Girl said, "Look, I'm a smart girl. I don't have time for a boyfriend, but a talking frog..... now that's cool!"
