Robin Williams

Robin Williams is an American actor and stand-up comedian.

History
When an ozone hole was over Springfield, residents were advised to stay inside unless they either wore sunscreen or had a class 9, or "Robin Williams", level of hair coverage.

He was mentioned by Lenny at Moe's Tavern. He apparently was having dinner at the restaurant with his children and he wasn't making his children laugh.

He appeared in a dream of Homer Simpson's where he said that Stanley Kubrick wanted him to star in The Shining.
