So, years ago (circa 1993, I think), I was looking around at alternate rules systems; something for our groups to play that wasn't AD&D2, Rifts, or WoD. I happened across some of the "silly" games, which we'd play as one-off or two-off sessions for some levity after particularly daunting campaigns. I recall having some fun with Macho Women With Guns, but the one game we'd spent most of our double sessions on was Tales from the Floating Vagabond; three system was easy enough, and the exploitation of tropes from the world of film and comics was always good for a laugh. Combined with the fact that you could make any sort of character you wanted (from a wizard to a cyber-knight, caveman to college professor) and they could all be in the same adventure party, have us awesome freedom.
The game was published by The Avalon Hill Game Company, and seemed to disappear after they were purchased (by Hasbro, IIRC). A couple years ago, the creator posted the PDF of the game on DriveThruRPG, which was great, but now he's relaunched the game with a Kickstart campaign. I'm hoping that this will fund and stretch, so I'd encourage folks to give it a look. I'm excited to see what he's brewed with the extra 100+ pages. http://www.kickstarter.com/projects/452329082/tales-from-the-floating-vagabond-second-edition/
