Being a huckleberry

Over the holiday weekend I saw Tombstone (which was pretty good) and Val Kilmer, who plays Doc Holliday, has this line where he says, "I'm your huckleberry" with a long Southern drawl. In the context it means, "I'm the one you're looking for." For some reason, I can't get it out of my head. I just want to say it all the time now.

Man (responding to crisis): "Does anyone know CPR?!!"
Meg (sauntering up, drawling): "I'm your huckleberry."

Woman (behind espresso machine): "Who had this grande soy latte?"
Meg: "I'm your huckleberry."

It's sublime.
