Here's your hilarious joke:

A crazy man walks on to a bus and starts repeating, (Warning: this is a math-y joke) "There will be the coming of days. You believers will be integrated, you non-believers will be differentiated." He starts pointing at each passenger saying, "I integrate you! I differentiate you!" Everyone was scared but one man just sat there coolly with a grin on his face.   "Aren't you afraid?," said the crazy man. The other man chuckled and said, "Sir, I am not afraid. I am e^x."
