I think the set-up now is better than the days of old (when it had that guy that used to sit on the sofa where the guests are cos he was annoying). The setup of Ross and 'Four Poofs and a Piano' is much better.
I think my fave episode of this was the one that had Jim Carey and Johnny Vegas on aswell where they were singing 'Wild Thing' I think it was at the end of the show.
