EDIT:
Well, I went and created #catfish on freenode this morning. Anyone that would like to try realtime chat is welcome to join and see what it is all about.
There are several IRC clients available, some free, some not.
Free versions include: Chatzilla, a Firefox addition.
https://addons.mozilla.org/firefox/16/
X-Chat (this is built using the binaries that are open & GPL’d)
http://xchat-win32.berlios.de/?page_id=6
Commercial clients include:
mIRC. A very robust client that has been around forever.
http://www.mirc.com/
Klient. This is probably a little easier to set up than mIRC and has a lot of configurability also.

At any rate you can join after installing on the above clients (or one of your choice) by clicking here:
irc://irc.freenode.net/#catfish
Note: before you can join, you need to register your nickname – see http://freenode.net/faq.shtml#nicksetup for detailed info.
BTW Brian, did you catch state record lastnight?
