Don't even think about it!

Don't even think about it! is a phrase commonly used in the United States when a person denies another person something. Usually the phrase is used as a proactive response to a question that before any question has actually been asked, as in: "It is not worth your time formulating that request I can see that you want to ask me be because I will deny you it".

In 1995, Shaquille O' Neal, a popular basketball player, made a Pepsi commercial in which the phrase was prominently used. The commercial begins with Shaq at a street court playing hoops, and a little kid notices him. Then the kid exclaims Shaq's name, and Shaq, noticing the kid has a Pepsi on his hand, walks over and says 'Hey, can I have it?'. He bends over, supposing that his admirer will give him the soda, but then the kid, out of nowhere, says Don't even think about it!!. Then, a musical sound simulating that of a scratched record erupts, ending the commercial with the Pepsi logo and slogan.

This commercial was rather popular, and it was shown on TV for about three more years.

The commercial is actually a parody of another famous commercial from the 1970s produced by Pepsi's rival, Coca-Cola, in which a young boy meets football player Mean Joe Green as he is leaving the field after a game. The boy gives his hero a bottle of Coke, and in exchange for the drink, the football player throws his towel to the boy, who excitedly catches the souvenir.
