Regarding the Bush/shoe-throwing incident, I want to point out that I was one of the very few people who managed to avoid making any of the hundreds of possible puns derived from the several shoe-terms that have homonyms and multiple meanings. Of course, I'm just too straight-laced to enjoy puns.
Relatedly, I was also struck by how every bit of news coverage made a point of saying how in Arab cultures throwing ones show was an insult. Noz and Boing Boing reacted similarly to the ubiquitous expression of the obvious, but perhaps we all overestimate American understanding of Arab culture. After all, they hate us for our freedom, right?
