I've never heard people say things like "I know you're just joking, but you should be a little more woke in mixed company," in the same tone.
If you want a concrete example from something that was actually published, this is from Jonathan Rosenbaum's 2002 review of the movie Far From Heaven,
The black bar and nightclub operating in the sticks with plenty of clients and a dance band in the middle of the afternoon is simply ridiculous, though part of this conceit could have been borrowed from The Bridges of Madison County. (Haynes is more convincing when he shows us a gay bar in downtown Hartford and when he takes the politically incorrect step of showing us a grotesquely affected gay dandy at the art gallery.)
That said, I'm pretty sure that the first time I ever heard it was in Politically Correct Bedtime Stories, published in 1994, which is making fun of political correctness.
