Yeah, it's obviously when the pig comes to life during the dinner party scene & terrorizes Delia. In the current version it pretty much just lunges at her repeatedly but in DC it rubbed its curly penis (very prominently displayed) all over her face.
It was too much. It's crazy enough that a roast pig comes to life & tries to attack the hostess. Like that should be the joke & the wild happenstance in the scene. Adding the penis assault bit was just gratuitous... and kind of gross. I remember people laughing a lot but I thought it was dumb & forced & really sophomoric. They lost nothing by cutting it. There's still a roast pig that attacks a woman during a dinner party, just not sexually so.
I guess this isn't really a spoiler since it was removed from the show... but maybe people don't realize that the oversized puppet pig will be coming to life. LOL You never know.
