An old man was walking down the street when a frog hopped up to him and said, "If you kiss me, I will turn into a beautiful princess."
The old man took no notice and walked on. Astonished the frog hopped after him. "I said, if you kiss me I will turn into a beautiful princess and I'm all yours."
The old man walked on and took no notice. In desperation the frog hopped after him and screamed at the top of its voice, "If you kiss me, I will turn into a beautiful princess, and I'm all yours and you can do what you like with me."
The old man reached down, picked up the frog and put it in his jacket pocket. Then he continued on his way.
Frustrated, there came a muffled cry from his pocket, "You've got to kiss me!"
The old man took the frog from his pocket and spoke to it, "Listen, at my age a talking frog is worth more."
