* AccidentalNightmareFuel: A common complaint about TheMovie is the evil Pat and Jess robots are too scary for toddlers, Postman Pat's target audience.
* EarWorm:
** The {{theme tune}} will not leave you.
** [[https://www.youtube.com/watch?v=vCypt7uyBQM Jess the Cat.]]
* MemeticMutation: ''Postman Pat's Banging Day Out''. A crude overdub video with gratuitous swearing, mild violence, and moderate sex references. Probably one of the earliest forms of YouTubePoop to hit the Internet.
** "He who leads shalt learn!"
** It seems that ''Postman Pat's Banging Day Out'' has inspired a cottage industry whose sole purpose is editing and overdubbing episodes of Postman Pat to insert profanity and risque references.
* TheyChangedItNowItSucks: Most people who watched the original as children (or even as parents) are horrified by ''Special Delivery Service''. HELICOPTERS?! AND A TRAIN?! AND ''[[ThatCameOutWrong ETHNIC PEOPLE]]''?! AND WHERE THE '''HELL''' ARE GRANNY DRYDEN AND MISS HUBBARD?!
** Averted with the 1996 episodes, which made people very neutral or just glad.
** And then there's the movie, which had parents wound up because of the evil Pat and Jess robots.
* ToyShip: Pat's son Julian and his friend Meera.
* UncannyValley This counts if you're not a big fan of stop-motion, particularly for season 1. You might even get caught off-guard by the close-up shot of Postman Pat's face at the beginning of [[http://m.youtube.com/watch?v=1uukgYgflCE the original intro]], which seems to come at you pretty suddenly.
* UnintentionalPeriodPiece: Not quite yet, but once [[UsefulNotes/HMTheQueen Liz]] dies all current episodes will be instantly dated by the presence of "EIIR" (Elizabeth II Regina) on Pat's van.
* ViewerGenderConfusion: Jess is a tomcat.
* TheWoobie: Katie's doll, Sara Ann. Katie loses her in the pilot, and it's up to Pat to find her.
