For me, usually lots of Rocky Top playing.
I actually have a CD, I can't remember what it's called, but it has a couple versions of Rocky Top along with a bunch of famous calls by John Ward and others.

The week leading up to the game I look forward to Chatt's "What Other Message Boards Are Saying" thread and The Official Girls of... thread.
On Game Day, I read Yankee's "Official Game" Thread.
Around noon (10am if it's a noon game) I crack open a bottle of whiskey and start slamming down Jack n Cokes
Like Freak, I play Rocky Top over and over!
