In the midst of 30 Rock's non-stop bashing of Boston, the crew revolted against Liz Lemon and NBC management's decision-making (ha!). So Liz, genius that she is, thinks of a solution that Jeff Zucker wishes he thought of first.
When there's a mutiny, invent a scapegoat! It's so brilliant in its simplicity. If Jeff Zucker just said it was all some guy named Joeyjojo Junior Shabadoo's fault, then he wouldn't have to have all the blame fall on him. And everyone can hate Joeyjojo while Zucker can simply watch NBC's empire crumble instead of watching it crumble AND taking the blame for it. Maybe the writers of 30 Rock should be running NBC?
