We just love it when celebs give up some of their time to do a PSA to help others.
We especially love when that cause is such a great cause like AIDS research.
We love it even more when that video is absolutely HIGHlarious!
In the video:
"Zach Galifianakis, Sarah Silverman, Tracy Morgan, Chloe Moretz, Marisa Tomei and Isaiah Mustafa let you know how we can all get rid of AIDS by 2015. ACTIONS. SPEAK. LOUDER. Go to ONE.org."
Check out the PSA (above) from FunnyorDie.com for some laughs and a good message.
