Trick or Treat is a British television show hosted by Derren Brown produced by Objective Productions and broadcast on Channel 4.

This distinction is not always obvious, however: in Series 2, a participant's dark experience of being persuaded to (supposedly) kill a kitten was a 'treat' because of the positive attitude to life Derren believed she would consequently develop; similarly, a volunteer who chose a 'trick' was kidnapped, but had been taught escapology techniques which enabled her to easily escape.

[1] To break up the stories of each episode, the series also includes separate routines with celebrities and also footage from the USA where Brown has been able to use his anonymity to try out new stunts.

In another part of the episode, a superstitious woman was tested on her beliefs by being made to walk on pavement cracks and under ladders, smash a mirror, etc.

A caption at the end of the show said that the episode was dedicated to her memory, having been killed on the way home from filming, although a continuity announcer later revealed that it was a joke.
