Actually, some pervert way before Caligula probably invented the upside-down throat fuck, but Gag Factor perfected it. I give Max credit for his groundbreaking gonzo in the 90's that I was totally devoted to then & Max even gave me a free pass to his website once (yeah, that's right Max), but barf is barf and that smeared make up clown shit is aesthetically gross, unerotic and depressing.
