Where's Mel Brooks' The Producers and Young Frankenstein? The Marx Brothers in virtually anything they made? Bringing Up Baby?
Also MIA is a film that could possibly out-do even the redoubtable Airplane for sight gags and verbal by-play, The Tall Blond Man With One Black Shoe (the original, not the horrid Tom Hanks remake). No Amazon Women on the Moon or Kentucky Fried Movie? (Untitled)? Nun on the Run? Better Off Dead? What's Up Tiger Lily? There's Something About Mary? Bananas? Some Like It Hot?
Geez, off the top of my head I can think of 50 movies funnier than some of the clinkers on their list.
That's the same mentality that has declared rap to be "music", and graffiti vandalism to be "art".
