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
hang out 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 be your girlfriend
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 be your
girlfriend for a whole year!". The programmer smiles and walks on.

Finally, the frog says, "What's wrong with you? I've promised lots of
fun with a beautiful princess for a whole year and you won't even kiss
a frog?"

"I'm a programmer," he replies. "I don't have time for
girls.... But a talking frog is pretty neat."
