Once upon a time, a beautiful princess happened upon a frog in a pond.
The frog said to the princess, "I was once a handsome prince until an evil witch put a spell on me. One kiss from you and I will turn back into a prince and then we can marry, move into the castle with my mom where you can prepare my meals, clean my clothes, bear my children and forever feel lucky for doing so."
That night the princess had frog legs for dinner.
A computer programmer happens across a frog in the road. The frog pipes up, "I'm really a beautiful princess and if you kiss me, I'll stay with you for a week". The programmer shrugs his shoulders and puts the frog in his pocket.
A few minutes later, the frog says "OK, OK, if you kiss me, I'll give you great sex for a week". The programmer nods and puts the frog back in his pocket.
A few minutes later, "Turn me back into a princess and I'll give you great sex for a whole year!". The programmer smiles and walks on.
Finally, the frog says, "What's wrong with you? I've promised you great sex for a year from a beautiful princess and you won't even kiss a frog?"
"I'm a programmer," he replies. "I don't have time for sex ... But a talking frog is pretty neat."
