Let’s hope this doesn’t ever apply to Hub & me (credit to http://lazybastard.ehuna.org/) :
Two engineers boarded a flight out of Calgary. One sat in the window seat, the other sat in the middle seat. Just before take-off, an accountant got on and took the aisle seat next to the two engineers. The accountant kicked off his shoes, wiggled his toes and was settling in when the engineer in the window seat said, “I think I’ll get up and get a coke.”
“No problem,” said the accountant, “I’ll get it for you.”
While he was gone, one of the engineers picked up the accountant’s shoe and spat in it. When he returned with the coke, the other engineer said, “That looks good, I think I’ll have one too.”
Again, the accountant obligingly went to fetch it and while he was gone, the other engineer picked up the other shoe and spat in it. The Accountant returned and they all sat back and enjoyed the flight. As the plane was landing, the Accountant slipped his feet into his shoes and knew immediately what had happened.
“How long must this go on?” he asked. “This fighting between our groups? This hatred? This animosity? This spitting in shoes and pissing in cokes?”.
