This.It wasn't even sad. It was so poorly executed and it didn't really deliver. The whole episode was blah, but that's expected when you watch Family Guy. I already said this, but Family Guy should never do a serious storyline.
Family Guy just got really stupid when they tried serious stuff. It's suppose to be a comedy, and not to say it's impossible to do serious stories, but the way they present them and the way the "humor" is ran through an episode, they just can't execute it right.
