kat says, "In all of the hundreds of postings we had about 9/11 while and right after it was happening, there was no thought of writing some sickening parody about body parts, etc."

Well, there was a thread soliciting sick jokes about it, which resulted in a song parody about contracting anthrax from terrorist activity, as well as a couple of jokes and an interesting discussion about using dark humor (or "shock-humor", as McGrath says) to deal with handling the corpses: Thread title – Jokes in the Worst Possible Taste

There's another dark-humor discussion, nestled among other posts, in this thread on the 9/11 terrorist attacks: AMERICAN ATTACKS**SIX -about enough huh?
