When Lucifer interrupts the taping of the show, one of the puppets says, "Mind your own business Doctor Who!" Tom Ellis previously appeared on Doctor Who (2005) as Thomas Milligan in Last of the Time Lords (2007).
Professor Docherty mentions missing Countdown, which she says has not been the same since Des took over, though she amends this to "Both Deses." This alludes to Des Lynam and Des O'Connor hosting the show after the death of Richard Whiteley in 2005.
