A Soldier and a Marine were sitting next to each other on a plane.
The Marine took off his boots and began to stretch out. The soldier swore under his breath at the Marine and told him he wanted to get up and get a drink.
The Marine insisted that since he was in the aisle seat he would get it for him.
The Soldier agreed, and when the Marine went to get his drink he started spitting in the Marine’s boots.
When the the Marine came back the Soldier nodded and thanked him for the drink, very pleased he pulled one over on the Marine. This happened several times times throughout the flight.
When the plane was descending for the landing, the Marine put his boots back on and quickly realized the Soldier had been spitting in his boots.
To the Soldiers surprise, the Marine was laughing about it.
He looked over at the Soldier and said "when are we going to stop playing these games, spitting in each others boots and pissing in each others drinks, it’s so juvenile!"
