Hyperscape Body Swap Ticket
From Tardis Wiki, the free Doctor Who reference
Clara Oswald had a Hyperscape Body Swap Ticket between her sticky notes in her room. (TV: Dark Water)
Behind the scenes
The ticket was featured in the 2013 Proms mini-episode titled in the credits as Doctor Who Proms Film. It was a special ticket which could swap its user's body to a new location, but without clothes. Sometimes it could also cut off some of its user's hair. On 11 July 2013, Clara and the Eleventh Doctor used these tickets to swap their bodies into the Doctor's own Prom show at the Royal Albert Hall. The Doctor claims he bought the tickets from a man from "Space Vegas".
