I don't know exactly what it is, but I love this episode. I mean, I can't specifically point to one thing, I guess it's just the whole thing overall. The Death character was really good, all of his back and forths with the Warners were hilarious. I like all the surreal imagery during the checker game and wherever it was they were during that sequence. I kind of like how there was a touch of sincereness at the end, when Wakko asks if they were serious about keeping them all together, even if it was just because Spielberg eats that stuff up.
