If you've never heard of it, and I hadn't, it's a mid-70s porn flick that was filmed in 3D. And it has John Holmes in it. Everything that you're probably imagining about it right now is true... but there's more!
It has three guys in Trojan soldier costumes trying to get into Troy. One winds up in a bunny suit, one in a chicken suit, and I'm not sure exactly what the third one is supposed to be. The director and writer pop in from time to time to talk about the action and try to figure out where to go next. There's a truly bizarre hotel clerk, car chase scenes, pie fights, and plenty of random sex scenes that just more or less drop into the film from nowhere.
Joe Bob says get drunk and then check it out.
