Uploaded on Jan 20, 2007's George Maschke speaks with Nick Frost about how to fool a polygraph (lie detector) test in episode 5 of the tongue-in-cheek 2003 television series Danger: Incoming Attack.

Note that the anal sphincter contraction, discussed as a polygraph countermeasure, while effective, is no longer recommended by, and alternative techniques such as mental countermeasures or tongue-biting are to be preferred. Note also that in his summary, host Nick Frost incorrectly characterizes the anal sphincter contraction as squeezing one's buttocks (which was and remains to be avoided).

Note also that polygrapher Bruce Burgess purports to know that "someone is messing around" based on the fact that Nick's chart showed reactions to both relevant and control questions. This is utter nonsense, however. Indeed, the polygraph "control question test" was developed in response to the realization that even innocent people might well react to accusatory relevant questions. The way one passes the "test" is to show stronger reactions to the control questions than to the relevant questions, and it is to be expected that a truthful person might show reactions to both kinds of questions.
