YouTube is holding its first-ever comedy week from May 19 to 25th, and they got Sarah Silverman, Rainn Wilson, Jake & Amir, the Gregory Brothers, and a bunch of people I’m not familiar with together to film this promo. They’re not in this promo, but Vince Vaughn, Seth Rogen, Michael Cera, Ed Helms, Garfunkel & Oates, and Norm Macdonald will also be participating in the event, a week of stand-up, sketches, music, and live performances, to finally bring some comedy to the serious, serious video site.
