I confess; I have a friend who is a graphic artist, and we printed, circa 1992, a number of "revised" safety briefing cards that I would drop in to various aircraft on my travels for work. DL MD-80s and 722s were frequent recipients. They illustrated various suggestions for a safe and comfortable flight, including the best positions in the lavs for *ahem*, the proper brace position and a prohibition against apes flinging poo when the "no poo flinging" lamp is illuminated.
Sadly, these were done by hand rather than on a computer, and my originals were lost in a move several years ago. I'd love to do the project again (and tailor it for both the times and my current carrier of choice/necessity), but I would hate to see what would happen if Thousands Standing Around were to catch wind of it.
