One happey day, e and e^x were out on a walk. All of a sudden, they saw a differential operator.
e turned pale in fear and quiveringly asked:
- Crap, what if he sees me? He'll turn me into zero and I'll disappear!
e^x sturdily said to his constant friend:
- I'll have a talk with him, he can't do anything to me.
So, e^x went over to the differential operator:
- Hi, I'm e^x. What's your name?
