The Sandwich Pact

Three construction workers were sitting on the bridge that they were building, having their lunch break. The first guy says, "If I get a Vegemite sandwich again, I am going to jump off this bridge." The second guy says, "If I get a peanut butter sandwich again, I am going to jump off this bridge." The third guy says, "If I get another strawberry jam sandwich, then I am going to jump off this bridge." The next day, the first guy gets a Vegemite sandwich, the second guy gets a peanut butter sandwich, and the third guy gets a strawberry jam sandwich. All three guys jump off the bridge and die. The next day at their funerals, the first wife says, "If he just told me, I would have given him a different sandwich." The second guy's wife says, "It is all my fault. If only I knew." The third wife says, "I don't get it, he makes his own lunch."
