If you've ever wondered how a filibuster works but haven't had the patience to sit down and actually watch one (Don't. They're pretty boring unless Wendy Davis is speaking.), fret no more.
Patton Oswalt stopped by the set of "Parks and Recreation" recently and improvised this hilarious example by talking entirely off the top of his head for eight minutes straight about what he thinks the plot of the new "Star Wars" movie should be.
My favorite part, of course, is Amy Poehler's interjection at 5:35.
