Ok, so an airman, a sailor and a Marine were caught with alcohol by the Saudis, which is a big no-no, and were sentenced to 50 lashes each. But the Saudi prince in charge of the punishment wanted to show mercy, so he offered each man one last request.
The airman, being the smartass typical to that branch, asked for a Koran to be strapped to his back prior to the whipping, thinking that the Arabs would spare him in order to not desecrate their holy book.
“Impudent infidel,” said the prince," we anticipated just such a profane trick from you, and instead you shall be scourged wearing your own Bible!"
So the Bible was strapped to the airman’s back, which, in any case, did little to protect him as the whip soon cut through it and lacerated him badly.
The Marine’s turn was next, so thinking quickly, he asked for two Bibles to be strapped to his back, and almost all the lashings were done before they were cut through and his back was only slightly lacerated.
When the sailor was asked for his last request, he said “I request not 50, but rather 100 lashes!”
“Ah, you are truly a brave man,” said the Saudi prince," and in recognition of this I will grant a second request. What shall it be?"
“Strap the Marine to my back!”
