No, that’s not a new episode title, just the merging of (apparently) two of David Tennant’s favorite things, in this music video shared by the production staff of Doctor Who. Not sure where it originated, we believe it was very cast centric and watched in house during Tennant’s years on the show, but thanks to @Georgesab for pointing us to it.
