What's a Bracket?

I joined the work pool bracket thingy for basketball or some other such sport.

So far it's fun.

Of course I had to ask for help on how to even get into the 'selection of teams' thing. But I blame Yahoo for that--"You have been invited to join the Wild Turkey Bracket. Please create a name for your Bracket." What the?

Anyhow, I figured it out. And chose teams. (Haha, Gonzaga, you have a funny name, therefore you will win a game. OOOO Kansas! I know a guy who used to play basketball for Kansas, therefore you will win too! Your team color is orange? no thank you.) And now I'm reaping the fruits of all my labor. I'm in 4th place. which puts me ahead of 4 other people...one of which is a big sports type guy.

But of course there are 4 games going on right now, and my teams are currently behind the 8-ball in all 4 games. Meh, what do you expect when you pick teams based off of logos?
