Worst Comedies of All Time

I guess FILM.COM has this list of the worst comedies of all time. Apparently over there at film.com the world started in 1984. Probably these kids are sheltered and don't know anything about movies from before E.T., though one of the authors, let's call her Molly Q. Millennial, says in a comment that the worst comedies are all from the past 20 years. I guess it never occurred to her that people thirty years from now will never have heard of Freddy Got Fingered. In general, the list is pretty uncontroversial, except for what kind of psychopath would include Who's That Girl on a list like this unless they were born after 1985 or before 1965? Also, it's not controversial to put All About Steve on this list, but I always felt that it was better than The Blind Side anyway, not to mention countless 'successful' romantic comedies like Sweet Home Alabama. Of course, I went into All About Steve expecting it to be bad so maybe my expectations were too low. I actually thought it was better than a lot of the movies of its sort. I mean, I haven't even seen New in Town, but I'm sure it's substantially worse than All About Steve. But why do people always have to be hating on Pat? Bullies, I say.
Anyway, I'd also suggest that Rhinestone (1984) transcends the conventional good/bad dichotomy, though I wouldn't necessarily go as far as saying I would watch the movie in one continuous sitting. Of course, this brings us back to what a questionable exercise it is to assert a supposedly objective evaluation of art. I'm willing to concede none of these movies are particularly good, with the exception of Who's That Girl of course, but I'm not sure it's a very well considered list of the the 'worst comedies of all time.' Which comedies have you seen that were more painful than these? For the record, the worst SNL films are Coneheads  and MacGruber.
