I thought the skit was perfect for what they were trying to do. They were trying to get all of the cast together to do the last sketch of the season. They also ended up throwing all of the backstage guests and walk ons to fill out the cast. It wasn't all that funny of a sketch, but I think it accomplished what it set out to do.
The Artie shout out was the only false note in the sketch. Artie looked nervous on stage during the credits, as if he felt he didn't belong up there or that he was being ignored by the cast. I didn't know the fat man could move like that.
