In what amounts to the greatest acting performance of all time, Robin Williams has announced that he has been Susan Boyle all along.

“I thought people would have figured it out sooner, considering how mannish she was. Good thing they didn’t get a look at the massive amounts of arm hair Susan had.” Said Williams in a press conference earlier today.

Williams readily admits that this attempt to reclaim star power is a thinly veiled and pathetic copy of his film Mrs. Doubtfire.

“Dressing up like an old, ugly British woman worked once before, so I figured I could try it again.”

The greatest surprise has been Mr. Williams’s singing ability.

“I’ve always been able to sing like that. But my career only required me to do impersonations of hot dogs and be manic, so it was unnecessary.”

Some question the need for this pop culture stunt. Mr. William’s career was thriving due to such popular films, such as RV, Man of the Year, and License to Wed. The Academy Award winning actor is even hearing Oscar buzz for his upcoming film, World’s Greatest Dad, directed by Bobcat Goldthwait.

This Susan Boyle stunt joins other great pranks by Hollywood, including Borat and Keanu Reeves’s film career.
