It's my feeling that fat "porn" isn't even really porn at all. If you go to the zoo and you see an elephant mounting another elephant, is that porn? No, because they're not human, they're just unthinking animals doing a thing. If you're walking at the park and you see a dog mount another dog, is that porn? No, again not human, just a couple of beasts. A jar of mayonnaise is incapable of producing porn, most of the time if it's "naked" you can't even see its parts nor tell its gender. Ah well, Homer's house is Homer's rules, what're you gonna do.
