There was a pretty dumb one for that Formula 409 cleaner. It said "the new 409 has 25% more giddy-up"
What the fuck does 25% more giddy up mean??
And speaking of commercials, I thought I'd share a funny one. They released the 2nd wave of previews for Hollywood Homicide, a movie with Harrison Ford, and during the preview it says "Harrison Ford is at his best" then it cuts to a shot of him screaming "YOU KNOW IT!" while humping and making horns above his own head. First time I saw that I was high and I almost shit!
