One tends to wonder about that around here from time to time...
Like I said, I LOVED the movie, but, then again, I find myself longing for comedy films that aren't just the same tired, recycled Adam Sandler or Will Ferrell vehicles (though I have found both of those actors, especially Ferrell, quite funny in the past). The majority of Americans, I've found, don't agree with me, and would rather have their comedy spoonfed to them in safe, familiar, bite-sized chunks. (And that's also why I don't watch network sitcoms. Ever.)
