I felt bad for Joyce, but in the end, she actually helped out Lois, who pulled a Ryan Seacrest.
There were some great jokes, Lois and Stewie at the grocery store, Bears in Space becoming Pigs in Space because Miss Piggy beat the crap out of Kermit, and Peter trying to give Consuela his number (usually I'd find it overly long, but for some reason, Consuela just makes me laugh).
That was funny, but there's no way he's Stewie's father, I mean, Stewie isn't nearly old enough to be the product of what happened on that set.
