Can't remember them all really lol
Most of them I've been subscribed to for many years and some since they first started around Youtube.
I subscribed to them mostly cause they have interesting content, funny stuff, or just generally enjoyable personalities. They are great to watch to get your mind off things.
I recommend these channels to anyone who is goofy and has an open mind and good sense of humor.
