Klito Bell
The Italian Batman porno, "Klito Bell", defies description... and lacks subtitles, so you don't know exactly what the hell is going on, except that the men's moaning is looped in the soundtrack, and there seems to be some sort of anti-American bent to the whole thing, but you can't tell quite what it is. Really, the opening sequence, wherein Batman rides his bike through the Italian countryside, is all you need to see.
