I am sad to have missed Panda Party 2008:

The first ever pandamonium party took to the streets last night with hundreds of pandas dancing in Union Square. The pandas hopped on the train and made their way to Williamsburg where the festivities continued. Unfortunately the NYPD decided that pandas having fun in the street were a threat and made several arrests angering the panda mob. Despite their best efforts the party continued until past midnight with boomboxes blaring and pandas partying in the streets!

Pandas. Awesome. BLAM.
