The Simpsons celebrated their 20th Anniversary Sunday night in Santa Monica with the evening's animated guests of honor Homer, Bart, Lisa, Marge, and Maggie Simpson on hand to walk the yellow carpet. They mingled with a few celebrity fans including Luke Perry, Tom Arnold, Brittny Gastineau and many more.

It was an especially busy occasion for Marge who spent the evening dodging questions about her scandalous Playboy Magazine cover... Simpsons executive producer, Al Jean recently told NPR, "Well, I talked to Marge today. She's a little embarrassed. She wanted people to know the photo is photoshopped. It's really the body of Wilma Flintstone."
