In English, it's just saying that the derivative of e to the x still magically equals e to the x. The joke is if you repeatedly club e to the x with d/dx you aren't changing it from e to the x. Most anything else you derive will come out a lot differently.

The proof is done pretty well here, if anyone wants to be a math nerd for a minute:

Google "derivative of e^x proof" and click the Khan Academy video to watch a short, entertaining proof.
Haha, I don't know why you would want to say it in English; I think your life will be fine either way :p

I mainly typed it out for people who might feel excluded from getting the joke. I *love* encouraging people who are dabbling in something like science or maths to keep learning because, to me, that stuff is super interesting.
Ah i see. I definetly want to get back to doing some math exercises on a regular basis again. Back when I understood math, I felt kinda smart and it was actually fun.
