probing for fuel

So....I told my friend as we were driving through the countryside that if he ever had the rare occurence of seeing a UFO, and knowing his rear gas problem....ahem....I told him not to fart while observing the alien beings....simply because, my friend, they might hear you and chase your lazy ass down and knowing that you're lazy, and not very fast- which wouldn't matter, they might probe your ass for fuel. ha. chew on that chewbacca
