A man was wearing a tin foil hat to work every day and refusing to take it off for any reason. Finally one co-worker got up the nerve to ask him why he was doing such a nutty thing.
"To protect myself from space aliens," he replied.
"You silly ass," his co-worker said, "There's no such thing as space aliens."
"See," the man smiled, "it works, don't it."
George Bush took us to wars in Iraq and Afghanistan to protect us from being attacked by terrorists. Um, it worked? Self protection Limbaugh style.
