I have never seen anyone get so angry at a 2 second joke they didn't getThis is pretty rude to be honest.
I'm not saying it has to be "spoonfed", I'm saying that the fact it's something shown for so little time and isnt something simple takes away from the joke for me.
Also, the joke just raises further questions that make it seem like a joke made for the sake of it rather than it thematically making sense.
'The joke is that this seeds and feeds shop used to be called sucks and fucks so it must have been some sort of sex shop or brothel'
It's a tenuous premise that is not simple enough to get an instinctive laugh and is also so convoluted that it isn't just some easy, throwaway joke.
