All the great comedy shows have a balance of both. The Goons, Monty Python, Goodies, Benny Hill. But there are two secrets to good comedy - the first, as always, is timing. The second is over-acting - a little bit of over-acting is a dismal failure but over-the-top over-acting can be a great success. Over-acting by American "comedians" is embarrassing but over-acting by Monty Python et al is bloody hilarious.
