The panel of judges on any TV "talent" show. A bunch of berks all playing pre-determined characters and going along with a script rather than giving expert insight on what they've just witnessed. Might as well be Sky Sports.
There's always a pantomime villain, overly-harsh one. There to bring the boos. Then there's the over the top silly one, to balance things out and make people laugh. Then one or two stuck in the middle who try to be serious about proceedings, but not too serious, call them the vanilla ones.
