Now that it’s confirmed that Lance is older than Keith there better be TONS of “I’m older than you” jokes
Ngl do to Jack's background and some of his habits I head cannon he grew up extremely poor. So I see him as the guy who eats well done meat because that's what you have to do with cheap sketchy meat. His taste in beer is for the gross piss beer. It's not a vegetable if it didn't come out of a can. His eating habits suck because when you have no money you have no choice. God he probably microwaves ramen.
