An elderly economics professor is standing at the shallow end of the campus pool. A Coed is standing at the deep end taking pictures. She suddenly drops the camera into the pool. Then she motions for the professor to come to her. He goes and she asks him to retrieve the camera. He agrees and dives in and retrieve its.

Upon returning he says to her, “Why did you ask me to retrieve the camera when there were many younger and more athletic males closer to her?” She replied, “Professor you seem to forget that I’m in your Econ I class, and I don’t know anyone who can go down deeper, stay down longer and come up drier than you.”

When drawing up the guest list for a dinner party, inviting more than 25% economists ruins the conversation.

Economics is the painful elaboration of the obvious.
