I saw a snippet of "A Touch of Cloth" last night, which is a spoof (comedy) on Police Drama's. (the name itself is a play on almost soiling yourself with the words "Touch Cloth").
It came off as an Airplane like series, with a bunch of gags put in for entertainment.
However, the best Comedian for me (and I own all of his DVDs) is Lee Evans.
He's an impressionist too, so his faces are really funny when he makes the expressions. The only problem I have with him (although many fall into this), is that he tells a similar joke on each DVD regarding things in life that are funny. He's still funny in how he mentions these Slice of Life Jokes but you know he's done something like that before.
I also like Airplane and Airplane 2, although most of the jokes are for Americans (and possibly Canadians), so I don't get some of the jokes in the films.
Never watched Naked Gun but heard they're pretty good, and Scary Movie in general feels like watching a 12 year old's Comedy.
Tell me your favourites and thoughts on Comedies!
