Pantomime

Pantomime or "panto" was a traditional form of raucous British family musical theatre which often used naughty double intendres and word play aimed at adults. Bernice Summerfield once experienced pantomime come to life. During the incident, Wolsey changed into a real life version of the panto character Puss in Boots. (PROSE: Oh No It Isn't!) UNIT occasionally put on Christmas panto productions of Aladdin. (PROSE: Timewyrm: Revelation, No Future) Millie Peterson invited the Eleventh Doctor to watch a pantomime of Peter Pan with her mother and cousin, Louie Rollins, though the panto never took place. (WC: Snowfall)

The Doctor himself was once a player in a pantomime. Death's Head unwittingly discovered the Seventh Doctor portraying a jester in a Brighton pantomime, but the Time Lord was able to get off stage before the robot mercenary could find him. (COMIC: Time Bomb!)

Doctor Who At The Real-Life Panto (Cinderella For The Friday Night Project)
Ahead of his first guest host appearance on The Friday Night Project in January 2007, David Tennant, alongside regular FNP co-hosts Justin Lee Collins and Alan Carr, attended and took part in a panto of Cinderella at the Broadway Theatre in London that featured Kelle Bryan as Cinderella and Linda Robson as the Fairy Godmother.

During one scene, Carr and Collins played scary trees that Cinderella encountered in the forest - and when Cinderella asked the Fairy Godmother for help, the Fairy Godmother called for the Doctor. A full-size TARDIS mockup appeared from off-stage, and from behind it, Tennant emerged as the Tenth Doctor to the Doctor Who theme and raucous applause. Using his normal Scottish accent instead of the Tenth Doctor's Estuary English accent, he greeted the audience, explained he was in the Time Vortex when he heard the Fairy Godmother's call and decided to help and invited the two of them to take shelter in the TARDIS.
