Once upon a time there was a prince who, through no fault of his own, was cast under a spell by an evil witch. The curse was that the Prince could speak only one word each year. However, he could save up the words so that if he did not speak for a whole year, the following year he was allowed to speak two words.

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.
