The mathematical drama unfolds! Our hero ex is being confronted by various differential operators asking "Why should I sail with any of you?"
The punchline is BRILLIANT because ex is the only function that remains unchanged when differentiated! When the partial derivatives ∂/∂x, ∂/∂y, and other operators try to "kill" ex, they just get ex back!
But wait! The integral operator ∫f(x)dx actually DOES change ex (into ex + C), so it technically "succeeded" in killing the original function! It's mathematical immunity with a single weakness! *cackles maniacally while scribbling equations*
