Spoiler alert: This hoary joke has circulated for many years, so you’ve probably heard it before, and some people think it’s not even funny but that’s their problem.
Due to an airline reservation glitch, a doctor and a lawyer were seated together in first class. There was nothing they could do about it, as no other seats were available, so they settled in for the long flight. The doctor, who occupied the window seat, kicked off his shoes, lowered his backrest, and dozed off. The lawyer occupied himself by reading a magazine he found in the seat pocket.
After a while the doctor woke up, announced he had to use the lavatory, and asked the lawyer to get up so he could exit his seat. “No problem,” the lawyer said, as he stood up in the aisle. “Will you bring back a Coke for me?” “Sure,” the doctor said.
While the doctor was gone, the lawyer picked up one of the doctor’s shoes and spat in it, then carefully put it back exactly as it had been. When the doctor returned, the lawyer got up again to let the doctor back into his seat, taking the open can of Coke the doctor handed him and swigging from it as the doctor arranged himself in his seat.
“You know,” the doctor said after the lawyer was seated again, “the animosity between doctors and lawyers is childish and silly.”
“I agree,” the lawyer said. “So then,” the doctor said, “do you also agree it’s time we stopped spitting in shoes and pissing in Cokes?” The lawyer began retching as the doctor rolled his eyes and sighed.
