[Gooch1971]

Three professors from Cambridge face execution by the electric chair. The first one is strapped in and asked if he has any last words. He says, "I am from the Harvard School of Divinity and I believe God intervenes on behalf of the innocent."

They throw the switch and nothing happens, so they figure God must not want this guy to die, and they let him go.

The second one is strapped in and says, "I am from the Harvard School of Law and I believe justice intervenes on the part of the innocent."

They throw the switch and again nothing happens. They figure the law is on this guy's side, so they let him go, too.

The last one is strapped in and says, "I'm from MIT, and I'll tell you right now, you won't electrocute anybody if you don’t connect those two wires!"
