A young man 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 will stay with you for one week." The young man 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 for one week and do ANYTHING you want." Again the young man took the frog out, smiled at it and put it back into his pocket.

Next the frog yells, "Okay okay, If you kiss me and turn me back into a princess, I'll stay with you FOREVER and do ANYTHING you want." Again the young man took the frog out, then he chuckled at it and put it back in 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 forever, and do anything you want. Why won't you kiss me?"

The young man said, "Look I'm an engineer. I don't have time for a girlfriend, but a talking frog is cool."
