...throw it anyway.
Bush Ducks Shoes Thrown in Iraqi Leader’s Office
President George W. Bush ducked two shoes thrown at him by an unidentified man during a press conference in the Iraqi prime minister’s office.
Bush wasn’t hit by the shoes, one of which sailed over his head. The president shrugged and said “I’m OK” after the incident in Baghdad today. “All I can report is it is a size 10,” Bush said.
In Arab culture, throwing shoes is a grave show of disrespect. The man shouted an Arabic phrase, which an Iraqi present said translated as “this is a farewell kiss, dog.”
Another "grave show of disrespect" for Arabs is to to refer to someone else as a dog. It's about the worst thing you call someone.
