Our theoretical physics student: I have to do an assignment on classical field theory.
Me (hilariously): Oh I prefer the modern stuff.
Mr. Waffle (unwisely): What’s that?
TP student: Basically, electro and magneto statics and dynamics*
Me: Actually, I liked it better before it went electric.
Thank you and good night.
*Or words to that effect – electric definitely came in there somewhere.
