Behind the scenes
The NBC comedy featured Inspector Spacetime as a show-within-a-show which follows the eponymous Inspector and his Constables as they travel through time and space in their red phone booth, fighting enemies such as the Dalek-like "Blorgons", armed only with a quantum spanner, an analogue to the sonic screwdriver. A British programme, Inspector Spacetime is said to have begun in 1962, thus making it the oldest sci-fi show on television. Several standalone webcast episodes of Inspector Spacetime were later created.

The cosplayers in Selfie are actually dressed as Troy and Abed from Community when they cosplayed Constable Reggie and the Inspector from the 1980s "Inspector Spacetime Christmas Special". (The colouring of Constable Reggie's costume is inaccurate.)
