Bob Ross is an extremely well-known painter who hosted The Joy of Painting, a painting show on PBS. A very noteworthy attribute of Bob Ross is that he can paint a proper landscape in less than 30 minutes and constantly describes the objects in his paintings as "pretty" and "happy". /b/tards generally love him despite the fact he's the opposite of a /b/tard.
If you want to take a nap on a Saturday afternoon, all you need to do is put on his show and you'll be asleep in a few minutes. When you finally wake up, a beautiful landscape will be displayed on the TV for you to enjoy.
