Few days ago an US Marine and a Russian General were talking at the beach The Marine says to the General: "we have the greatest submarines on earth. We can last under water for several weeks." The Russian interrupts:"no way our latest submarines last for 6 months without seeing any daylight." The both stop talking as they are surprised by a submarine approaching the beach. A soldier jumps out raising his arm straight in the sky, yelling:"Hail Hitler we need Diesel!"
