That's okay! In the song they're talking about, a part of the hook is "You got to know when to hold em, know when to fold em" and the origami joke was about the folding part.
I hope somewhere, somehow, someway, that Griffin knows that I am playing Persona 4 right now. I have leveled up Chie Satonaka, she has leaned Bufu, and I have used it in boss fights. And I will be thinking about the Gambler for the rest of the game.
What Kenny didn’t know is right before The Gambler asked for some of his whiskey is that he downed a handful of Percocet right before, and he was planning to kill himself.
It's a metaphor we are all gamblers every single day playing the cards we are dealt and making the best we can out of our luck playing the game our way!
