Homer's failed attempt at building an outdoor barbecue leads him into the world of outsider art.

!! Tropes:

* BookDumb: When Homer tried to read the assembly instructions in French, he got stumped at "Le Grille".
* ItsTheSameNowItSucks: Happens InUniverse, as Homer's second art piece is panned by critics for being too much like his failed barbeque.
* LeaningOnTheFourthWall: After Homer badmouthes MattGroening, a huge pencil with eraser seems to erase Homer, but it's just two guys carrying a really huge pencil.
