Bingo... "roleplaying" is part of the genre name, after all.
And I'd say whatever extra knowledge I have over you in D&D is balanced out by my lack of knowledge about recent television... I didn't even know there was a new Scrubs!

New Scrubs (on Disney+) is similar to the old one, but some characters are not in it and they have new ones.

D&D does seep into general culture. It's even had the odd movie. Mind you, all sorts of games and toys are getting movies. The studios like to trade on known brand names.
