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 will stay with you for one week."
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 I'll stay
with you for one week 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 for a week and do anything you want!"
The engineer said, "Look I'm an engineer. I don't have time for a girlfriend,
but a talking frog, now that's cool!"
