There are a handful of channels I watch daily but not a whole lot I rewatch unless I'm showing a friend or something.
Only ones I can even think of that I've rewatched a few times is Marble Hornets and this video about The Mouse Utopia Expirements by Down the Rabbot hole or something. The later is very interesting and I'd recommend it.
Edit: if I wasnt anout to clock back into work I'd post link sorry peeps!
