Homer, Marge, Bart, Lisa and Maggie bobbed down the yellow carpet Monday night outside the Roosevelt Hotel as Fox celebrated the 500th episode of “The Simpsons,” the longest-running animated comedy on television.

Wearing a simple blazer and yellow shirt, of course, series creator Matt Groening dedicated the momentous episode to the animators at Film Roman who give form to the citizens of Springfield week in week out.

Persona non grata Julian Assange makes a cameo in the episode that sees the Simpsons banished from Springfield only to find a better life beyond its walls, though it’s not long before their old neighbors descend on the exiled family to shakeup their idyllic new life.

Street artist Shepard Fairey came out to celebrate the long-running animated series, which became a sort of ritual before he developed his trademark graphic style.

“For many years I worked seven days a week and the only time I would take a break was on Sunday to watch ‘The Simpsons,’ ” Fairey said.

Next to the roulette and craps tables, Weird Al Yankovic sipped water and chatted up “MythBusters'” Adam Savage while Blink-182 bassist Mark Hoppus played blackjack with his wife.

Other guests took pictures in front of a nearly untouched pile of Homer’s favorite pink donuts and sipped drinks like passion fruit ‘Marge’aritas.
