Rowan Atkinson is the best on the list.
If I need a pick-me-up, Ill watch any episode of his Blackadder Series. The ones with George IV and WWI were by far the best. He and Hugh Laurie are just fantastic together.
I agree Black Adder is a great show. It has been many, many years since Ive watched it and Im about due for a fresh look. Brian Blessed was fantastic, just as he was in I, Claudius.
