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."
