Well, again, not pirate, but new show on Cartoon Network called Frisky Dingo. It's one of the funniest/oddest things I've seen since Space Ghost: Coast to Coast went off the air. When I first saw the following clip, I instantly declared it the greatest moment in television history. It's even funnier when you're actually into the show beforehand, but... still the greatest thing on TV!
