if I were a physicist I would simply not become death the destroyer of worlds

I've found that a way to get them to stop is to explicitly lampshade it:
"But what if a dude leaps out at you to kick your ass?"
"Oooh, I love playing this game. Okay, what if he's only doing it because he thinks I'm my as-yet-unknown evil twin, and - after the confusion is cleared up - challenges me to a zeppelin race across the Sahara?"
"Be realistic."
"Your scenario doesn't happen much in my life either."
