The latter is very '70s and the mom joke and its line delivery feel very much like something someone would say in 2017.
EDIT: I can’t articulate it well, but there’s a prominent humor style these days where people say awkward, uncomfortable things that aren’t in and of themselves funny at all, but because they’re said awkwardly we’re supposed to think that they’re hilarious. I know that’s inarticulate, but hopefully someone will get what I mean.
