Look at all those funny people!
The Office's Kate Flannery, Clueless star Donald Faison, Modern Family's Ty Burrell, even Tenacious D made an appearance.
Dramatic actors tickled their funny bone too because Breaking Bad's Bryan Cranston attended, along with CSI: Miami hottie Eva LaRue, plus Chris Lowell and Ahna O'Reilly from The Help!
That's not all either. The Jersey Shore's Pauly D and NFL player Terrell Owens couldn't resist an evening of laughter and music for a good cause.
The charity event was organized by Rogen and his wife, Lauren Miller, who have both been working with the Alzheimer's Association for several years since the disease has been affecting their family for multiple generations.
