What you've got 'ere is ya classic case of mob mentality combined with the overexcited self-oblivious nature of American young boys who seem rather validated in their fandom of Rick and Morty who think that everything they do together must therefore be funny and intelligent because what they so dearly have bonded together over is considered funny and intelligent by enough of the 'right' people that they cannot be wrong, no matter how entitled they want to act over limited edition sauce from a throwaway line in one episode.
It's sort of like the 'cake' syndrome of Portal if any outlet ever decided to think it a good idea to market a limited edition of said 'cake' and kinda really meant the 'limited' part. You'd see the same childish group behaviour.
I'll add Fight Club groups to the list also. And Apple fans that camp overnight for the next phone, because, seriously....dude....what the fuck is with that? What the fuck is wrong with you? Are you hypnotised that easily by marketing?
To be honest though, the police were called to what, one outlet in the US? Is this really worth denouncing the whole show and fandom? I know many who love the show and they don't give a shit about the sauce, acting like a twat in public or even pushing their love of the series onto others. Maybe online or US takeaway stores are a different story for fandoms, I don't know, tend to avoid those places.
[small]Admittedly, it really is irritating when specific fans with no imagination or sense of humour feel the need to parrot quotes from their favourite entertainment together, like a compulsive instinctual reaction. It reminds me of looking after cockerels, the annoying dumb fucks. At least with those, the authorities don't care if you kill and eat them. And when Rick started pushing a certain 'catchphrase,' all I could sense sadly were a thousand future cockerels latching onto it for no other reason than because they were told to.[/small]
