Unlike most hidden camera shows, many of the scenes in "Trigger Happy TV" do not revolve around trapping normal people into embarrassing and impossible situations. Instead, he often makes fun of himself rather than others, and many scenes made people stop and either laugh or simply wonder what was going on; the passers-by are never made aware of the fact that they are on television. Such scenes include Joly answering a gigantic novelty mobile phone and shouting at the top of his voice into it (normally in quiet locations like golf courses, cinemas, libraries and parks), a chef chasing an actor in a large rat costume out of a restaurant, and two actors dressed as masked Mexican wrestlers getting into spontaneous fights in grocery stores. Other scenes included people dressed as animals breaking into a fight and the progress of various costumed pedestrians (such as a snail and an old man) across a zebra crossing in London. Joly also often dressed as a Cub Scout, a foreign person with bad English, or a park attendant.
