Actually, I thought “Sandy Passage” (the Grey Gardens spoof) was a laugh riot, but it probably only would be for people familiar with the original. Still, completely hilarious (especially when it decides to spoof another genre along the way). I found the Errol Morris TBL parody the least funny simply because the more we hear about our justice system, the more we realize how such a riff isn’t always too far from the truth. So this comes the closest to social commentary more than comedy, per se.
