What are the Odds?

Phil: What are the odds you'll drink straight soy sauce?
Elizabeth: One in ten.
Phil: Three, two, one...
Phil and Elizabeth together: Seven!
Elizabeth: Aaaggghhh!
Phil: Laughs heartily as he hands Elizabeth a small dish with soy sauce on it, and watches her wince while she drinks it.
Such was the scene I observed yesterday, of these two love birds in my kitchen.

What are the odds?
It's a game all of my kids enjoy playing. Maybe yours will, too!
Here's how it goes: Person One thinks up an action for Person Two to do, and asks what the odds are that they'll do it.
After careful consideration, Person Two states the odds: one in "whatever", depending on how much they do or do not want to perform the proposed action. For example, if you said to me, "What are the odds you'll eat this peanut butter chocolate chip cookie?" I would probably say, "One in one." Because I want to eat that cookie! But if you said, "What are the odds you'll put peanut butter in your ear?" I would probably say, "One in five-hundred." Because I really don't want to put peanut butter in my ear. (And because I am not very adventurous, and would therefore choose very big odds.)
Next, Person One counts down from three, and then One and Two simultaneously say a number within the given odds.
If they say the same number, Two has to do what One proposed.
If they say different numbers, Two is off the hook.

It's kind of like the game "Truth or Dare" which we played a lot when I was a kid.
I like this version more, though, because it gives the players more control over whether or not they have to do the "dare".
And it's fun to watch the anticipation of Person Two as One is counting down to Two's fate. *wink*

So, what are the odds you'll teach your kids how to play this game???
