An engineer was crossing a road one day when a frog called out to him and said, "If you kiss me I'll turn into a beautiful princess".


He bent over, picked up the frog and put it in his pocket. The frog spoke up again and said: "If you kiss me and turn me back into a beautiful princess, I'll stay with you."


The engineer took the frog out of his 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 princess, I'll stay with you and do ANYTHING you want." Again the engineer took the frog out, smiled at it and put it back into his pocket.


Finally the frog asked: "What is the matter? I've told you I'm a beautiful princess that I'll stay with you and do anything you want. Why won't you kiss me?"


The engineer said: "Look I'm an engineer. I don't have time for a girlfriend, but a talking frog? That's cool!
