Dressed Like Cancer, Henry Winkler Dashes House of Cards

(This video features Larry David.)

Most sobering situations could use an inappropriate joke. Contributing to Stand Up to Cancer's "This is where the end of cancer begins" campaign, celebrities use donated airtime to make us laugh, not bum us out. See spots:

"Cancer patients and their chemo-induced baldness have stolen the sympathy that is rightfully mine." And that's why Larry David can't get laid.

Meanwhile, Henry Winkler plays cancer in the style of Epuron's infuriating Wind guy. "Did I bite you? ... I didn't mean to."

More videos at the Stand Up to Cancer website, including one where the Daily Show says FU to cancer, and one where Katie Couric ... well, "Katie Couric" should be enough to make you laugh, actually.
