If you like Gervais, you'd appreciate how he handles charity stuff. See if it's on YouTube; I'm at work and can't check properly.For Comic Relief last Friday there was a sketch where someone wanted to do an Opera version of The Office and went to see Ricky for his blessing. Ricky sits in his office, gnawing at a whole chicken and keeps quoting examples of his success and takes the piss out of celebrity charity fundraising!And for Children in Need last year (I think) he filmed an African sequence. Except unlike other celebrities, he didn't actually go, he just filmed it on a green screen!
There is also a bit of a great charity routine of his in Grand Theft Auto IV!
The guest stars, while they do have great lines and are hilarious in how they are portrayed, often as the opposite of the image they project, they do not take center stage, and are there to give an air of realism to the whole side of Andy being an extra on movies.
