Well, we learn something new about this family every week. Apparently, the Simpson family is 1/64th black (AND 1/64th Canadian, eh?).
As far as the episode itself, while I wasn't totally in love with the plot, there was really funny stuff squeezed in between the flashbacks. Especially at the start with Willie and Bart blowing up the tree stump.
Bart: Here comes the MYKIA! Willie: The wha? (Stump falls on Skinner's car) Skinner: My Kia!
And the ending was pretty good too. Homer toasting to his alcoholism is always good for a laugh.
I'm gonna let you finish, but my pink shirt demands your attention!
The father and son have a touching death scene, punctuated by the Dad acting his death-gasps out loud at the Best Buy table. The Warcraft guys eye him warily. One of the kids then asks what they do now, and Eric says they can finally play the game.
