My buddy's uncle laughed at a funeral joke I told in 2019 and someone at the wake heard me
He told me flat out at the church in Akron that my dead-dad joke was the thing that finally made him cry that week, and now I genuinely can't tell if that was a compliment or a warning about where the line sits.
That line about "cry that week" is the whole thing right there, because crying at a funeral isn't a bad sign, it usually means the joke did its job and let some pressure out. If his uncle was the one who laughed in 2019 and then said that at the wake, he's telling you the joke landed the way jokes are supposed to at these things: it gave people permission to feel something. My advice is don't read it as a warning, read it as a green light for that family, and save the riskier stuff for crowds you already know.
