Two doctors had boarded a flight out of Boston, one taking the window seat and the other, the middle seat. Just prior to take off, an attorney boarded and took the aisle seat next to them.
The attorney kicked off his shoes and had no sooner settled in, when the doctor in the window seat decided he would get up and get himself a coke. The attorney said, "No problem, I'll get it for you."
While he was gone, one of the doctors picked up his shoe and spat in it.
When he returned with the first doctor's coke, the other doctor decided that it looked so good, he would like one too.
The attorney said he would go and get one for him. While he was gone this time, the other doctor picked up the other shoe and spat in it.
When the attorney returned, they all sat back and enjoyed the remainder of the flight. As the plane was landing, the attorney slipped his shoes on and knew immediately what had happened.
"How long is this going to continue?" he asked. "This constant fighting between our professions. This lack of respect. This animosity. This spitting in shoes and pissing in cokes!"
