To be fair, Barney appeared drunk in "The Blunder Years", but everyone counted it against the episode.
So the Bart kissing thing is from a future episode? Hmm...interesting...
It seems that this and "The Dad Who Knew Too Little" are my two favorites of the season, both Lisa/Homer episodes. That said, I'm looking forward to "Scuse Me While I Miss the Sky."
And DoTheBartman, you liked "Helter Shelter" more than "Spelling"? :-O
