Facebook CEO Zuckerberg to guest star on 'The Simpsons'

His hot young company just surpassed 500 million users.

He’s about to be portrayed in a major Hollywood film.

Yet nothing says you’ve hit the big time like being asked to voice yourself on “The Simpsons."

Mark Zuckerberg, the 26-year-old phenom behind the world’s most popular social networking site Facebook, will play himself as a guest voice on the iconic Fox television show this fall.

In the episode, "Loan-A Lisa," Lisa decides to help fund Nelson's new bike company. While attending a convention for entrepreneurs, the two meet Zuckerberg, who reminds the kids just how many famous billionaires like himself have dropped out of school.

Zuckerberg is in good company. Amazon.com’s Jeff Bezos made a cameo last season on an episode called "Billionaire's Retreat." "The Simpsons" has also mocked Steve Jobs and Apple fanboys.

We hear the episode will air in October just as “The Social Network” rolls out to screens nationwide.
