When I was a freshman in a red-state college, I had a professor who taught Newtonian physics with a super thick Russian accent. The student body was unusually conservative for a state college, so there was a sort of general bemusement about learning physics from a Russian, but even back then the Cold War was far enough in the past that not even the red tribe was inclined to stir up trouble about it.
He was aware enough of this to get off on trolling the class, though. Whenever some force diagram in a homework assignment needed to be weightless, instead of being some generic spacecraft it would be “Mir” specifically. And he’d always use ‘cosmonaut’ instead of ‘astronaut’, that kind of thing.
One day about halfway through the semester, he’s doing this with in-class examples on the board, and one of the students finally gets up the guts to troll back a little. So this kid shouts from the back of the auditorium, “Hey professor, what’s the difference between a cosmonaut and an astronaut?”
And this beautiful man spins around on one heel to face the class, whiteboard marker triumphantly over his head, clearly having been waiting for this moment the entire semester:
“Cosmonaut go to space first! Ha!”
