I like multiple:
-MinutePhysics/vsause/quirkology for when im bored and am about to fall asleep

-Vitaly/Romanatwood/magicofrahat/BFvsGF for when i wana see pranks

I used to watch Syndicate, whiteboy, xjaws, relaxingend, spiderbite, yoteslayer(cry), and some others when i was a big gaming nerd.

Now i just stick to the ones i posted and i just surf on the YouTube's popular videos and watch those
