Buffy the Vampire Slayer might be long gone (sadly) and Doctor Who doesn't return for a few more weeks (darn!), but that doesn't mean that you can't smush the two together into something as fun as a jaunty bow-tie. In this case, this means mashing the familiar opening credit sequence of Buffy with the visuals of the Matt Smith-era Doctor and his companion Amy Pond (Karen Gillan), with a special appearance by Alex Kingston as River Song, of course. You can watch this lovingly crafted homage to both Buffy and Doctor Who below. Season Six of Doctor Who kicks off on April 23rd on BBC America.
