1982 Burger King Christmas Commercial with Lea Thompson, Elisabeth Shue and Sarah Michelle Gellar

This was the first ads in which the business being promoted names their competitor and makes a specific charge against them. In this case, it was Burger King claiming that their burgers had more meat than McDonalds. Unfortunately, the claim was somewhat inaccurate, McDonalds sued Burger King, the Ad Company, and the 9 year old Sarah Michelle Gellar for libel. Gellar was sued because she uttered the words. After several months, McDonald agree to drop the suit against Gellar. The child Gellar loved McDonalds so she was doubly happy as she had been going to McDonalds wearing disguises after being sued.
