I was running an Amber campaign. At the conclusion of a dramatic, political story arc, I figured I'd run a session in which the player characters end up in the Seasame Street shadow (shadow being Amber-speak for "alternate dimension"). And that was the end of that campaign. We didn't even finish that session.

Oh, now I can't play Roland the headless thompson gunner?
