I recommend Just for Laughs Gags and Americas Funniest Home Videos. If you're in a bad mood, or just down, you will at some point end up laughing when watching these. :)

If you enjoy modern parodies check out Bart Baker. If you like to learn about random things, tedx / tedtalks. If you want to hear original raps check out ERB (Epic Rap Battles of History).

Watchmojo is another great one. Their channel is dedicated to mainly top 10 lists that span a wide range of topics from gaming to historic events to TV shows. They have loads of content.

And what's even better is that the lists are quality.

But really only the Board James and The Angry Video Game Nerd portions. Some of the other sections have good videos but some are rather boring.
