Add it, watch it, love it. It's from Edgar Wright, Simon Pegg, Nick Frost, Jessica Hynes, and a ton of other insanely talented British people. Shaun of the Dead, Hot Fuzz, Scott Pilgrim vs. The World... none of these things would have happened without Spaced. Do it. You are welcome.
(Here's where I would have embedded this Spaced clip if YouTube would let me.)
Thanks to Ryan Gallagher for the heads up.
