These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Backdoor Pilot Sort Of. Notice how the last 2 episodes of Series 2 feature Max & Paddy much more heavily than the rest of the series. Fast forward a few years and the duo get their own Spin-Off in Max & Paddy's Road To Nowhere which revolves around the motor home Max buys at the end of Phoenix Nights.
As well as call-backs to established Peter Kay memes, Phoenix Nights notably started the association of Peter Kay with the classic Tony Christie song "(Is This The Way To) Amarillo", which culminated in the song being re-released with a new video starring Peter Kay and a parade of British pop culture icons and getting to number 1. Max and Paddy are singing along to the song whilst driving a minibus, much to the bafflement and/or disapproval of their passengers, an Asian Elders group.
Paranoia Fuel For the first few episodes of his employment, Brian's convinced that Ray Von is a psychotic murderer and the evidence just seems to keep piling up.
