Crossing the road one day, a man heard a frog call out to
him “If you kiss me, I'll turn into a beautiful princess.”
The man picked up the frog and put it in his pocket.
The frog tried again, saying, “If you kiss me and turn me
into a beautiful princess, I will be your loving companion
for an entire week!”
The man took the frog out of his pocket, smiled at it, but
then returned it to his pocket.
Getting desperate, the frog yelled out, “If you kiss me and
turn me back into a beautiful princess, I'll stay with you
for a YEAR and do ANYTHING you want!”
Once again, the man took out the frog, smiled at it, and
returned it to his pocket.
Finally, the frog cried out, “What's the matter? I've told
you that I'm a beautiful princess, that I'll stay with you
for a year, and that I'll do anything you want. Why won't
you kiss me?”

The man patted the pocket affectionately. “I'm an engineer.
I don't have time for a girlfriend, but a talking frog is
cool!”
