I've mentioned my fondness for Rick and Morty, the funny new 'toon created by Community's Dan Harmon.

On Monday the Adult Swim series airs a fun Christmas episode featuring guest appearances by John Oliver and Dana Carvey. (The regular cast is pretty funny, too, and includes Chris Parnell and Sarah Chalke).

Today I have an exclusive clip from that ep, titled "Anatomy Park." As you can see, it looks like this story is pretty focused on anatomy; the main storyline involves Rick and Morty trying to save a homeless man.

Rick and Morty airs Dec. 16 at 10:30 p.m. ET. (On a related note, Oliver returns to Community next month. He talked to USA TODAY about it earlier this week.)
