Thanks to Matt (Mr. Beer) in chat for these! 

Also, as a side note, I'm looking into organizing a fandom-wide finale chat on the Avatar Olympics site on the night of the finale.  If you have a good chat script to recommend, email me at   I'm also considering using just an IRC client, so if you have knowledge of that please let me know as well!  And we will be in need of mods for the night (we want to control the spoilers in the live chat) so also send me an email if that's something you would like to do!  Thanks!
