  e^x and a constant were walking down the street, when up ahead they see a differential operator.

The constant screams, "Ahh, I'll be reduced to zero," and jumps into the bushes.

e^x says, "Ha, I am not afraid," walks up to the differential operator and says, "Hi, i am e^x."

The differential operator smiles and says, "Hi, I am d/dy."
