Steven Universe: Say Uncle is a Crossover between Steven Universe and the cartoon Uncle Grandpa.
While I don't particular care for Uncle Grandpa, and I was bit worried about this episode, it was actually pretty good. This episode is FILLED with jokes and was really funny. My favorite part was when Uncle Grandpa said"Don't worry kid, this is all non-canon", meaning that this show openly states that this in not part of the Steven Universe storyline. I give this episode 4 out of 5 stars
