Bob Ross and H. R. Giger
Few people know that Bob Ross, host of The Joy of Painting (PBS), had a nine-month apprenticeship with H. R. Giger in the mid 1980s. The relationship ended on a sour note*, but Ross painted nine Giger-inspired canvases while studying in Switzerland. Unfortunately, all nine paintings were were destroyed in a fire in Prague in 2006.
*Ross claimed that Giger was "demonic" and playing with "wicked magic." Giger told Le Monde, "Bob had a mental breakdown. He needed to go home."
