There is literally nothing you cannot find on the Internet. During a conversation with my wife I thought of a scene from a movie I had seen decades ago. (I didn't remember when or the name of the movie.) I only remembered that it starred Burt Reynolds (among others) and he attended some kind of a meeting during which participants weren't allowed to take a break, not even to pee. My wife and I are of an age during which the "wee hours of the morning" have real meaning. With a little help from DuckDuckGo (my favorite nonpartisan search engine) I found the name of the movie (Semi-Tough) and YouTube provided the scene (link provided - jump to the 7 minute mark). You can't get much more obscure than that!
