You never HEARD of Bob Ross - man you have to watch his shows. I remember when he died, a week or so later there was a tribute in one of the comic strips - "The Far Side" I think - there was a picture of an easel with what was obviously Bob Ross crushed under a tree in front of it, and a RIP
Being you have never seen one of his shows, when he was doing his paintings, he was always talking about "Happy Little Trees"
