Xbox Live Marketplace - Sea Life Safari, plus free Attack of the Show, SpongeBob and The Middleman

This week, Xbox Live Markerplace is short on freebies, but there is the free Best of Olivia episode of Attack of the Show (one of the programs I watch via SlingPlayer when I work at home). There's also a free pilot for The Middleman and a SpongeBob SquarePants show (if you dig deep enough; it's under the Play and Win section, not the featured Pest of the West episode!).
