A good bit, like Spongebob, Steven Universe, Adventure Time, Regular Show, obviously Invader Zim, Avatar the last Airbender, and especially Gravity Falls, which explains my repeated use of Bill Cipher in my comments. Gravity Falls was the show I was referring to in this meme, as I have just finished it last week. If you haven't seen it yet, I highly recommend it. Oh, and Rick and Morty, I recommend that too.
