An old guy was walking along a lake, when a frog looks up and says, "Hey Buddy, can you do me a favor?".

The old guy looks down in disbelief, and the frog says, "Yeah, you. Can you do me a favor? You see, I'm not really a frog. I was a beautiful princess, but a wicked ogre turned me into this frog. If you kiss me, I'll turn back into a princess."

The old guy looks dubious, so the frog says, "If you do that for me, I'll spend the next week with you in bed, and I assure you that you'll never forget it."

The old guy stands for a few seconds, then he stoops over and picks up the frog and puts it in his shirt pocket and heads for home. So the frog sticks her head up out of his pocket and asks, "Hey! Didn't you hear me? You have to give me a kiss! I'll turn into a beautiful sexcrazed princess just for you!"

The old guy says "Yup. I heard ya. But at my age, I'd rather have a talking frog."
