Good idea:

You get knuckle tattoos where it’s like how people do Love and Hate or Good and Evil but on one hand it says Coke and on the other it says Pepsi (the S and the I are on the same knuckle), but also you’d have to memorize the Love and Hate speech from Night Of The Hunter/Do The Right Thing and replace those two words with Coke and Pepsi.

Then you convince Coke to pay you to do the speech and they make a commercial out of it. But get the tattoos first because you’ve got to get your foot in the door somehow.
