The pleasures of YouTube—celebrity meltdowns, dancing dwarves, the eternal battle between man and gravity—have until now been small and private. Tonight, they become large and public, thanks to the Northwest Film Forum, which is presenting a curated collection of YouTube's greatest hits. As NWFF puts it, "What better reflects our culture than rampant access to very little bits of lots of things, irreverence toward copyright laws, and the idolizing of everyday folks doing silly things?" Nothing. Go. (Northwest Film Forum, 1515 12th Ave, 329-2629. 11 pm, $8.50.)
