Sarah Silverman, Zach Galifianakis Join Funny or Die for 'AIDS 2015' PSA [VIDEO]

The folks at Funny or Die are at it again, this time using humor to promote a serious cause. The comedic creative team (co-created by funnyman Will Ferrell) has joined forces with One.org in a campaign for “The Beginning of the End of AIDS by 2015”. In a PSA, Sarah Silverman, Zach Galifianakis, Marisa Tomei, Tracy Morgan, Isaiah Mustafa, and Chloe Moretz speak for the future, 2015 to be exact. Silverman tells us “boobs are gross”, Tomei demonstrates how eating with one’s mouth open is now sexy, and Morgan describes all the new conflated animals that roam the planet.

Laughter aside, there is a serious message to be conveyed.

“Now more than ever, we must recommit ourselves to achieving specific goals by 2015 that will help us bend the curve of this pandemic: end mother-to-child transmission of HIV, provide treatment to 15 million people, and drastically reduce new HIV infections,” One explains on its site.

"Please get off your lazy fucking Western asses and think about the rest of the world for one goddamn minute, and stop worrying about your pathetic life and watching The Bachelor. No one gives a shit," Galifianakis says at the end of the clip.

The PSA will be released during the International AIDS conference happening in Washington, DC until July 27th. Watch the clip below, and visit One.org to get involved.
