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!
