User blog:Surf2kona/Family Guy Episode?

I am trying to find an episode, with a hilarious cutaway, but I can't remember anything else about it.The were some sickenly sweet scene, and then a cutaway to an old lady saying how much she enjoyed that scene.

In another cutaway within that cutaway, Peter is screwing a pig and says something like "How do you like this you old bag?"

Anyone remember which episode that was?

Thanks,

Chas
