"A Boy and His Frog"

 A boy 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 boy
 took the frog out of his pocket, smiled at it and returned it to his
 pocket.

 The frog then cried out, "If you kiss me and turn me back into a
 princess, I'll stay with you and do ANYTHING you want."  Again the boy
 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.  Why won't you kiss me?"

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