On a joint military exercise, three soldiers shared a tent. The conversation turned to food. "In the Russian Army, we get 2,000 calories per day," said the Russian.
The Englishman responded, "In the British Army, we get 4,000 calories a day."
The American bragged, "The US Army gives us 8,000 calories."
The Russian laughed. "Nonsense!" he snorted. "No man could eat that much cabbage!"
