I don't subscribe but I watch these:

1.) ERB (14.9M)
Real and fictional characters duke it out in a rap battle. Batman vs Sherlock Holmes is probably my favorite. Sherlock's simply too good here.

2.) GothamChess (4.3M)
Chess game analysis. There's probably a better channel but this one's the funniest imho.

3.) Gamer's Little Playground (2.66M)
Video game cutscenes. A lot of irrelevant non-story segments got trimmed here.

And some more that I can't recall now.
