An English soldier, an American soldier and a Russian soldier found themselves sharing a tent while on a military exercise and the conversation turned towards 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?"
