I haven't heard of many of the people on the list either, but Andy Dick I know. I'm a huge fan of the TV show
NewsRadio (
http://www.imdb.com/title/tt0112095/) and I've seen the bonus stuff on the DVDs. Andy Dick is truly, completely insane. There is no other way of putting it - he got kicked out off William Shatner's Roast for licking guests.
I'm not sure why it bugged me that Jolie / Pitt's kids were listed separately, probably because I actually like the couple. :-/
