Some people earn money by creating hilarious youtube videos. I think, that is not going well with OP. 
It's about more than asking for a cut.
As I said "There are some really great people on youtube but there are also some really terrible people." "I don't blame any of them in particular."
then who are you blaming? the companies that pays those people who are terrible on making videos?
those companies dont care about what is in the video, what they care about is the popularity of it.
