I have done all kinds of automotive repairs thanks to youtube.
But often, late at night, I watch comedians. There's a channel, DryBar Comedy, that has standup that can be funny from time to time. And then, there's the usual group of British comedians: Jimmy Carr, Stewart Lee, Stephen Fry. And Christopher Hitchens is fun, speaking to us with his wonderful acerbic insights from beyond the grave.
I'm not really awake, so that's the best I can come up with before hitting an adequate level of caffeine intake.
