Hehe.
My personal favorite commerical is the one where a couple is in a restaurant, and they husband has to go to the bathroom so the women stays in her seat, suddenly this man she doesn't know sits down it her husband's seat and starts eating his steak. Then when he's done he gets up and goes away right when the husband comes back. He looks at his empty plate and he asks his wife "did you eat my steak?"
Of course, they other guy was eating it because is had something or other brand steak sauce.
