I don't have a huge problem with dangling participles; I'll often say things like "Speaking as a linguist, that sentence isn't grammatical", where it's obviously not the sentence that's speaking as a linguist. (See various Language Log posts from Geoff Pullum arguing that avoiding danging participles is typically a matter of politeness as opposed to grammar.) But the following sentence from the government's anti-childhood-obesity website is priceless:
Cauliflower? No problem. Roasted with garlic and olive oil, the kids happily munched as if they were fries.
It doesn't help that the only plural antecedent for "they" is "the kids"; but, man, they really ought to have a copyeditor over there.
