Name the show/episode?

A good few years ago I saw part of a cartoon, where a family built a nuclear bunker in their front lawn. A girl from the family got upset and went and sat in it, unaware of this the family concreted over it and built a barbecue pit on it, before inviting their neighbours round for a bbq. At this bbq, a disabled man was removed from his wheelchair briefly for some reason I cant remember, and a baby went something like "yes, the human part has finally been separated from the machine, now is my chance to try its powers" before sitting in it then being removed from it by his mother.

Id like to find out what it was so I can watch it again. Naturally from the evil baby, neglected daughter and wheelchair guy I presume it was family guy. However, extensive googling has thrown up no results. I am now wondering if it was southpark instead - I never never knowingly seen SP so I cant tell.

Anyone got any clues?

Talking baby?

Family guy I guess.

You remembered wrong!

S01E05 A hero sits next door (Family Guy of course)

Has the scene with Stewie (the baby) getting into Joe's wheelchair at a BBQ, there was no nuclear shelter.
Meg's in it too, she was probably upset but didn't end up concreted into a fallout shelter!

Hmm I obviously have a few cartoons confused! Is there any FG episode where meg does get trapped in a nuclear bunker?
