What da fabled humped companion of da "displaced Arab" should have employed to avoid his turban-wearing master's realizing dat he was also present inside da tent.
Just like da hilarious kiddie-joke about "look for peanut shells to determine if there's an elephant in bed wif you", I seriously doubt dat using camelflage would have helped said shivering dromedary to avoid detection by his comfy-warm desert-companion, since even if he did indeed appear virtually invisible, da Arab would still have FELT his towering pack-animal's enormous bulk squeezing inside da tent wif him. :P
Wearing patchy-black-and-white-colored clothing would actually make you show up very starkly against ordinary backgrounds; you would need to remain among a "herd of Holsteins" for said camooflage to be effective at concealing your presence.
That guy was wearing his orange and yellow BDU's, he was ready for war on the sun and y2k, even though neither one ever happened. What is he going to do with his orange camoflage now?
