An engineer was taking a walk when a frog spoke to him and said, “If you kiss me, I’ll turn into a beautiful princess.” He picked up the frog and put it in his pocket.
The frog spoke again and said, “If you kiss me and turn me back into a beautiful princess, I’ll become your girlfriend.” The engineer simply continued walking.
The frog spoke again and said, “If you kiss me and turn me back into a princess, I’ll become your wife.” Again, the engineer took no notice.
Finally, the frog said, “What is the matter? I’m a beautiful princess. Why won`t you kiss me?”
The engineer said, “Look, I’m a busy engineer. I don`t have time for a girlfriend or a wife, but a talking frog, now that’s cool.”
