The Simpsons meet Adventure Time in the newest couch gag, which will accompany The Simpsons' 28th season premiere Sunday night. It wasn’t directed by Adventure Time creator Pendleton Ward, but it’s a darn good imitation. Ward does, however, sing the song.
Every character (except Lisa) gets a new identity as a character from Adventure Time, and the action gets weirder and weirder as the sequence goes along. See how many small details you can find that tie the two shows together. -via Geeks Are Sexy
