Muntadher al-Zaidi, the Iraqi journalist who threw his shoes at George Bush and spurred some of the greatest animated GIFs in Internet history, explained in court why he did it: “the former American leader’s ‘bloodless and soulless smile’ and his joking banter provoked him.”
Get it?!
“Soulless” … “sole-less” … Shoes have soles. Bush’s smile need a airborne-helping of sole.
Also, had the shoe hit his lip, it would have bloodied his smile, too. It’s a pun about how Iraq needs more blood donors. Very highbrow and socially-conscious, like a Victor Borge performance.
