A lawyer was cross-examining the doctor about whether or not he had checked the pulse of the deceased before he signed the death certificate. "No," the doctor said. "I did not check his pulse." "And did you listen for a heartbeat?" asked the lawyer. "No I did not," the doctor said. "So," said the lawyer, "when you signed the death certificate, you had not taken steps to make sure he was dead." The doctor said, "Well, let me put it this way. The man's brain was in a jar on my desk but, for all I know, he could be out practicing law somewhere."

Insect electrocutor

In 1910, the first U.S. patent for an "electric insect destroyer" was issued to William H. Frost of Spokane, Washington (No. 974,785). The invention used a number of electrically energized parallel wires such that a flying insect passing between them would complete the circuit by bridging the wires with its body and electrocute the insect. The patent describes using fine wire and tensioners to keep the parallel segments taut. The charge on the wires could be supplied using an induction coil and a battery. The form of the device could be as a flat frame, or as a cylindrical arrangement surrounding a light to attract the insects into the charged cage.
