I've already seen this recced all over, but I should add my voice to the throng: Cat's in the Cradle by daasgrrl. It's House & BBC Sherlock & Fortysomething, and it's one of the best constructed-reality vids I've ever seen, up there with Killa's Closer and Laura Shapiro's Hurricane and various other greats, IMO. It plays on the fact that House and Sherlock are both derived from the same literary source, and Hugh Laurie (House) and Benedict Cumberbatch (Sherlock) played father & son in Fortysomething. I loved it even though I only know one of the three sources. It is a slice of vidding perfection, truly.
