Briggsback Mountain
An X-rated western film starring dwarf artist Briggsy as a gay cowboy who rides across the plains wearing only pink chaps and stetson. He is on a constant quest for cowboy ass. He lassos unfortunate lone horsemen and fistfucks them to oblivion, shouting "yee-hah" all the while.
Keep away from Briggsy's local gay bar or you'll end up with a cameo in the sequel to Briggsback Mountain.
