throw a shoe at someone with views you don't like:
Howard Dean, the newly minted leader of the Democratic Party, and former Pentagon adviser Richard Perle made clear their opposing views on the war in Iraq during a debate marred by a protester who tossed a shoe at Perle.
Perle had just started his comments Thursday when a protester threw a shoe at him before being dragged away, screaming, "Liar! Liar!"
How can anyone disagree with that ironclad logic?
