Ah, this explains everything. When Sean “Diddy” Combs announced yesterday that he was joining the cast of Downton Abbey as a series regular, he was actually promoting a new Funny or Die short that digitally adds the hip-hop mogul to existing Downton footage. (You can insert him anywhere!)
The jokes are predictable — Diddy keeps calling the show Downtown Abbey; at one point, he fights off Thomas’s advances; there’s a decent amount of swearing — but funny all the same. And you’ve got to admire the chutzpah of a guy who never misses an opportunity for product placement, even in a spoof video.
