Similarly, when Homer is a missionary, you see him walking along the beach drinking from what appears to be a coconut.
“Are you enjoying your ox testicle?” one of the natives asks.
“Yup,” he says.
“Are you sure you wouldn’t prefer a coconut?”
“No, I’m good,” Homer replies.
Some of these are legitimately gross, but some are still damn funny.
The Eye crust thing. I can’t watch it. I doesn’t help I saw that before I had Laser Surgery.
I can’t believe noone mentioned the treehouse of horror where the family shrunk themselves to go into Mr. Burns body, but Homer doesn’t get out in time. He expands and is wearing the living Mr. Burns like a suit. Truely disguesting.
Maybe that episode was shown after most of the posts in this thread, which were in 2002.
The Treehouse of Horror when they were serving “fresh meat” in the cafeteria:
You might say there’s a little Ute in all of us.
I didn’t notice that. My bad.
But aside from that, it’s still pretty disgusting.
Ewww - exactly! That and the snake Smithers gulping down Mr. Burns. I shuddered at both.
Actual line is “More testicles means more iron.”
Actual wording on cylinder is “Assorted Horse Parts- Now With More Testicles!”
The scene where the Simpsons go to a seminar about living cheaply which ends with everyone chanting, “Squeeze every penny! Squeeze every penny!” Homer takes a penny out of his pocket and squeezes it in his hand. He squeezes so hard it goes under his skin and travels up his arm.
Oops, didn’t notice this thread had a first page and someone’s already mentioned this one. Still, my nomination stands.
Now I’m wondering what the ‘alf Pong’ retro video game would be like. 
alf’s head would probably be the pong ball. But what about the paddles??
The most disgusting ones for me are:
Mr. Burns suckling on a mole along with her babies.
Bart’s toad-monster
Mr. Burns sucking in his lung after it popped out in a car accident.
Sherry Bobbins. She’s an original character, like Ricky Rouse or Monald Muck.
