An English soldier, an American soldier and a Russian soldier found themselves sharing a tent while on a combined military exercise and the conversation turned to how well fed each of them was.
“In the Russian Army we have 2000 calories of food a day,” said the Russian.
“Well,” said the Englishman, “In the British Army we are given 4000 calories of food a day.”
“That’s nothing,” said the American, “in the US Army we have 8000 calories of food a day.”
At this the Russian got very annoyed. “Nonsense,” he said, “how could one man eat so much cabbage?”
