A young man was crossing the road when a frog called out to him and said, "If you kiss me, I will turn into a beautiful princess." The man took the frog, smiled at it, and put it in his wallet.
The frog called out again, "If you kiss me and I turn into a princess, I will live with you for a week and do everything you want." The young man took the frog out, smiled, and put it back.
Then the frog called out, "Okay, okay! I will be with you and do whatever you want forever!" The young man laughed and put it back in his wallet.
Finally, the frog asked, "What is wrong with you? I'm offering to be a beautiful princess! Why won't you kiss me?"
The young man said, "Listen, I'm an engineer. I don't have time for a girlfriend, but a talking frog is pretty cool."
