Two soldiers somewhere in Macedonia hunkered down near a stone-walled building for a much-needed rest.
"Say, Bud," said the first soldier, "that looks like a cell phone sticking out of your pack."
"Yeah, Bob," Bud admitted. "I keep it there in case our regular communication equipment fails and we need to call in reinforcements."
"Bud, I hate to pour sand in your canteen," Bob said after a moment's
thought, "but we ARE the reinforcements."
