Way back in the 1970s, boys and girls, The National Lampoon was a magazine, not a movie studio, and it was one hell of a wild ride of a magazine. People did not think of National Lampoon as a purveyor of bottom-feeder movies as they do today (such as Awesomest Maximus,” which is covered in my book Slavegirls in the Movies and On TV: The Hottitude of Servitude). It was full of some of the wildest, funniest, edgiest, zaniest stuff being done, by some of the best comedy writers of the time (much as Cracked.com is hoovering up a lot of the best comedy writers on the Web). National Lampoon Magazine produced a whole slew of top comedy talents: Doug Kenney, Hank Beard, George W. S. Trow, Chris Miller, P. J. O'Rourke, Michael O'Donoghue, Chris Rush, Sean Kelly, Tony Hendra, Brian McConnachie, Phil Russell and John Hughes – and many others.
Well when National Lampoon decided to produce the “Encyclopedia of Humor” in 1973, one of the little bits they came up with was “Cowgirls At War,” a truly twisted comic book mashup of WWII adventure comics, true romance comics, cowboy comics and bondage comics. The imagery was mostly WWII fighting and bondagettes dressed in cowgirl outfits when they weren't entirely naked, and the text was all true-romance cliches. Comic artist Russ Heath drew it, Micheal McDonald wrote it.
It was fricking HILARIOUS!
Above is a panel from it. And here's a link to the cover (scroll down a bit to see it).
