Yeah, I’ve heard people riff on that kind of thing—“Insta Ham” as like some shady, black-market ham app. It’s the perfect dumb premise: like you’re meeting a guy behind a Walgreens and he opens his coat and it’s just prosciutto and ibérico. But I don’t remember an actual specific, famous bit from the show that’s exactly “Insta Ham.” It sounds more like the kind of quick throwaway joke someone would make in conversation than a known, established joke.
