I had a roommate who would binge watch that guy's videos in his room and when he came out I'd make jokes like hey how's Elmer Fudd doing? Roomate didn't like that (honestly I just thought they were more of his goofy ufo vids at the time) but he does have a pretty damn good channel regardless of rhotacism. I also like Anton Petrov on YouTube whose angle is more about recent developments in astrophysics: https://m.youtube.com/user/whatdamath
