Chillin’ Island
Super dumb and non consequential but goddamn if its not mellowing. Perfect show for any kind of burnout or blahs
Relaxing Footage with Joe Pera
Joe Pera Talks You to Sleep
There was another one I forgot the name of on Adult Swim that was just like videos of rivers/streams, fireplaces, and other relaxing elements put to a lo-fi girl style soundtrack. Look Around You? Or something like that. When they started that one, I used to fall asleep to it nightly.
Edit: Not Look Around You; that was the BBC science show parody. Also good, but not the relaxing thing I am thinking of.
