Punch and Judy

Punch and Judy was a traditional puppet show.

After the Endovorms killed several civilians in Trafalgar Square, a Punch and Judy stand was abandoned, with the fleeing puppeteers still wearing the characters. (ST: The Lions of Trafalgar)

When the Sixth Doctor commented that Astrolabus was mad, he responded by hitting him repeatedly with a puppet he called "Mr. Punch". (DWM: Voyager)

Behind the scenes
According to REF: The Brilliant Book 2011, a non-narrative source, when the Fourth Doctor was trying to get rid of a Cybermat, the young Winston Churchill thought it was part of the puppet show he was watching.
