"I'm game (so to speak)."
"Game" is a colloquialism perhaps some of our members may not be familiar with. Reminds me of joke about some football jocks out hunting. They met a sexy bimbo, and said: "We're hunting for game. Seen any?"
She said: "No, but I'm game!" So they shot her.

I wonder what figure of speach "I'm game" is.

So who's going to throw out the first ball in of troy's new game?
