In Iraq, throwing a shoe at somebody is the ultimate insult.

So the question must be asked: What object, thrown, is the ultimate insult in other countries?

In France, of course, it’s a waffle....

Who’s to say why, exactly? Some say the waffle’s association with Belgium is enough to disgust any Frenchman. Others suggest it is its annoyingly spongy consistency....

[In] Chad... hitting someone with a pair of pants is the highest form of insult....

In the former Soviet Union it is not uncommon, especially among the savage Russian mafia, to throw a 68-ton American-made Abrams M1A1 tank....

In Peru, meanwhile, people throw their voices as a form of insult...

[In] Bhutan... people throw brightly colored tissue paper...

Surely, you can think of some better examples. So many countries. And don't forget the 50 states.
