Muthathar al Zaidi, an Iraqi journalist, threw both of his shoes at George W Bush as he completed his prepared remarks congratulating himself on the "Surge"™

From Erdla, in comments:
This is the gift from the Irakis this is the farewell kiss you dog.
This is from the widows, the orphans and those killed in Irak.
