Is there a name for the trope of something topical but not strictly necessary happening incidental to a punchline like the microwave in the last panel?
I know I’ve seen it in other places, but the only other instance I can think of is the people saying “I am a consumer whore!” “And how!” in the Rejected cartoon, and I’m not even sure that qualifies.
Maybe a few things that happen in the asdfmovies too, but they often introduce a recurring gag or a different joke entirely.




The universes where each and every would-be hero is terminally stomped for merely thinking about going on a quest are uncountable.
There are countable subsets where something other than that happens, and one of those subsets is where the universe rules provide enough wiggle room for a hero to win.
It is all but certain we live in one of the former. Stories about the latter give us hope that we might not be.
