Not sure if you have checked out the Gritty Reboots YouTube page, but it is exactly what the name implies. They take cute and cartoonish things and give them, um, well, gritty reboots. While I found all of them hilarious and enjoyable up to this point, their most recent gritty reboot of Adventure Time blew my mind and left me speechless.
Literally, I have nothing else to say. This speaks for itself.
Okay, ONE more thing to say: wow. Right in the feels.
