I also love the Kenny Roger's Roaster's episode, where Jerry switches apartments with Kramer because of the red neon sign.
There's a part in there at the end where Jerry catches Newman over at Kenny Roger's buying chicken and he's got some broccoli and Jerry knows he's not buying the chicken only for himself, but also for Kramer, who's supposed to be boycotting the place because of the sign, so Jerry says "if it's for you, then you won't mind eating some broccoli." Newman says "gladly" and puts some in his mouth and starts chewing. Then he spits it out violently, shouting "VILE WEED!", at which point he knows he's been caught.
