Key and Peele are always funny, and often hilarious. And this series of sketches lightly mocking Neil deGrasse Tyson is definitely the latter. In fact, it’s one of the funniest things I have seen for a long time.
To understand the joke, you will have had to watch Cosmos: A Spacetime Odyssey, or at least be aware of deGrasse Tyson’s presenting style.
As long as you get what’s being mimicked, seeing these two get deGrasse Tyson’s mannerisms on film so accurately is extremely entertaining.
That’s not to say deGrasse Tyson isn’t an excellent communicator. He is. But having such a unique style was always going to make him a target for comedians.
