I just wanted to say that I agree with Annie completely. I think it is all a matter of who the subject of the cameo is. If you know that a person will be offended, then it is better not to do it.
But I also really agree with the knowing your audience point. A lot depenends on who you are writing for/speaking to. In an acedemic situation I would not mention to my class that I have once had a (ok more than just one) beer with a duck on the bottle and made up a song about it
. But in a cameo fic that is supposed to be funny, I might use it. I agree that it all depends on your audience rather than a blanket statement about always erring on the side of caution.
