Patton Oswalt

It's Friday, July 12, so to celebrate it basically being the weekend (in our brains, at least), celebs spent the day being far too humorous for their own good. Or shilling their own stuff, but we don't care about that nonsense.

One of the double-feature 'Parks and Recreation' episodes airing tomorrow (April 18) has a cameo from comedian Patton Oswalt, who was tasked with ad-libbing for a full eight minutes during a scene in which his character uses a citizen filibuster to stall a Pawnee City Council vote.
