Behind the scenes Edit
The ticket was featured in the 2013 Proms mini-episode Bodyswap to the Proms. It was a special ticket that could swap the body of its user to another place, but without the clothes. Sometimes it could also cut off some of the 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.
