100 G'z in my pocket

Check this out. I promise to give you 100 grand for winning a radio contest. Instead I give you a candy bar called 100 grand. You bitch and moan and take me to court. What happens next? Please limit your answer to 3 bluebooks.

What other similar offers/tricks can you think of? Here are two to get the ball rolling:

Saying you'll give someone a car, but instead just give them a matchbox car.

Saying you'll give someone a blowjob, but instead, you just give them a job where they get paid to blow bubbles.
