Good Examples of "Genre" Comedies

I realized recently many of my favorite comedies could easily fall into other genres like fantasy or sci-fi. I think there's several reasons for this, one of the biggest being that when a comedy is forced not to rely on current events and memes it becomes a lot more timeless.

So what are you guys favorite genre comedies? I'll start the list with a few of mine.

Fantasy:
Disc World
The Tick (cartoon and live action)
Order of the Stick

Sci-fi:
Galaxy Quest
Red Vs Blue
Futurama

Historic:
Shanghai Noon/Knights
Black Adder
The Three Amigos

Horror:
Young Frankenstein
Shawn of the Dead
Ghostbusters

I look forward to some good suggestions.
