What is the worst joke in The Nutshack?

I'm kind of curious, since Nutshack is considered one of the worst animated comedy on television, which joke makes you recoil, feel embarrassed or just didn't really laugh at?

For me, it has to be the "Mega Dookie" scene... I fucking hate it with a burning passion and the show likes to remind me that it exists. I get it's supposed to be a satire on Japanese media... But I can't tell if it's just gross out humour or someone's barely disguised fetish.

Would like to hear your opinion on which is the worst!
