2 guys are walking up a sand dune in the desert.They have been lost for days, famished and on the brink of starvation
Man 1: "I can smell Bacon!".
Man 2: "Thats impossible, its the middle of the desert. You must be so starved your smelling things that arent there".
Man 1 runs over the dune and see's a bacon hanging off a tree, sizzling and succulent in the sun. Man 2 just stands there in disbelief while Man 1 runs over to the bacon tree. Then, all of a sudden, machine guns fire and riddle him with bullets. He falls to the ground in pain. Man 2 runs over to try and help.
Man 1: "Dont come any closer! Its not a bacon tree, its a ham bush!"
