True story: in Oakton, Virginia, in the late Eighties or 1990 or so, I rented the film from a video store, watched it by myself, and had the reaction you never want when watching a comedy: I thought Now why is this funny? I returned it to the store the next day, hoping no one in the family had noticed I'd rented it, but then someone in my family went Wait: didn't you rent History of the World Part I? and they re-rented it. I didn't join that viewing.
...I feel lighter now. Though maybe that's because I pooped earlier.
