Engineer is walking down a road. He hears "Hey! You! Help!" He looks around, and he sees nothing but a big frog by a puddle.
"Yeah, that's right, it's me, the frog! I'm actually a princess that's been cursed by a witch. You know that story, right? Well it really happened. Now I need someone to kiss me so I will turn back into a princess."
The engineer is surprised, then thoughtful. He picks up the frog and puts it in his backpack.
"Hey! Listen, you drive a hard bargain. But if you kiss me I'll give you a reward. I have some money."
The engineer thinks about it then keeps walking.
"OK OK. You do realize that I'm a beautiful princess, right? If you kiss me I'll stay with you and . . . uh . . . do anything you ask. Anything!"
The engineer thinks about some more then keeps walking.
"What do I have to do to get you to kiss me?" wails the frog.
"Well, I wouldn't know what to do with a princess," says the engineer. "But a talking frog is pretty cool."
