Joy of Painting
From Homestar Runner Wiki
Joy of Painting is an Easter egg on the Toons Menu. It is accessible by rolling over the video tape at the bottom of the TeeBee that reads "Joy of Painting". The video tapes have appeared other times on the site as well. It is not a real cartoon, but just a preview. It is revealed in the FAQ that The Brothers Chaps made it just so they could show Marzipan with a beard and afro.
Marzipan represents the late Bob Ross, the host of the show from 1983 to 1994, complete with beard and afro.
