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."
