You can choose which cast member you like to watch fall over, including guests that did the bit, on You Tube, I was amazed at the number of clips and entire shows that are cataloged there for Laugh In. I'm not a big You Tube user or watcher, but I did subscribe to a few cycling channels they offer and their various how-to clips for cycling are handy if you aren't sure how to do something mechanical, too. Maybe some of our trike and bent riders can put their own versions out here. My falling over on a conventional DF bicycle are boring, just bangs, bumps and bruises with some road rash thrown in for gore factor.
