Throw in some subtle nuance in the delivery, and I've done similar to basically call someone a jackass to their face.

For a rough example - attending a kids birthday party in the presence of racist ex-inlaws. Somebody says something predictably racist, I say something obnoxious which on the surface sounds like I might agree with them for half a second, then the realization hits that I was making fun of them and I roll my eyes and walk away.

I mean, you don’t have to get somebody’s humor, but it’s funny because of how shocking and absurd it is. The same goes for some racist jokes imo.

It subverts the expectation by calling the woman a dishwasher. This is the humour. I don't find it offensive because I assume they're joking, and it's a reasonable assumption because there is a real dishwasher at play while he referred to the woman as a dishwasher, making it quite clear he was simply joking and not serious positing that women belong in the kitchen.
