First thing I thought about was people stabbing each other and saying "thank you!" Some prisons celebrate that too which is funny in a way.
LMAO, thats even funnier than what I had in mind! Actually since I'm in the UK, we could celebrate that here with all the knife crime, oh the irony lol.
Funnily enough, a certain extremely evil person was put down in jail permanently by a good old fashion knifing too, which made a LOT of people including me happy, some actual justice right there. But that's a discussion for another certain section/thread ofc.
I actually meant OP Shanks although I'm not sure what it would actually involve except celebrating Shanks I guess? I just like the pun haha.
Thanksgiving always seems like such a nice occassion though, I envy the big lovely feasts especially too since I'm a glutton, but I love that it revolves around gratitude and even helping others potentially. Being thankful for food/harvests and such too.
