The last time I had trouble breathing in the movie theater was while watching <a href="http://imdb.com/title/tt0274166/">Johnny English</a>.
Of course, I don't really go for most of the people you listed. The Stooges annoy me, and Jim Carrey is sort of inane. Robin Williams is okay, given limited exposure and if you disregard certain films, and I'm not very familiar with many of the others.
So maybe it's like the fall of the Roman empire. You can argue that it happened, that it didn't happen, or that it was just a change of name and shift of location: Maybe the great comics of today just aren't doing slapstick. Maybe cynical sarcasm and <a href="http://www.comedycentral.com/tv_shows/thedailyshowwithjonstewart/">bitter mockery of current events</a> is the Great Comedy of today.
