I'm sorry to ask this, but since when has Family Guy been educational? They have a dog that has sex with women, a baby that makes gay stereotypes look overstated, and the father is a complete dirt bag ripoff of Homer from the Simpsons etc.
Family Guy pokes fun at pedophilia which I think is a step too far also. The show is so unoriginal it's a shame it's still going.
I've seen the episode and the whole vomiting act by Brian is straight out of The Crying Game, most of these shows, including SouthPark and the Simpsons pay homage to other movies. And the time lapse after the surgery was short, maybe they should have had Ida come back home already post-op, but they needed the extra fodder to make the tasteless jokes.
Is this in poor taste? I ask again, when is Family Guy not insulting anyone and anything? I wouldn't take it too seriously and I don't think the general public will.
Probably already forgotten the show as is.
