If you haven't caught up on Adult Swim's Rick and Morty, you should do that right away. It's one of the funniest, weirdest shows on TV right now - and is essentially Doctor Who, if the Doctor were drunk and embittered at all times. If that's not enough to get you onboard, I'm not sure what is.
But no matter if you've seen it or not, editing together sequences from Rick and Morty to make it look like Rick were rapping Eminem's ridiculously-wordy song Rap God is no small feat - and it apparently took Youtuber Benjamin Roberts about 100 hours to splice it all together.
The most impressive part? Rick manages to get through the whole thing without burping.
Although, as anyone watching Rick and Morty should know, there must exist an alternate universe where Rick IS the original artist behind Rap God. Since, ya know, there are alternate universes for everything.
