My class came up with this one today.

"Ordered pairs is like learning to run" (run in place) "before you can fly ( flap your arms like wings) Because you have to do x( cross your arms in the shape of an x) before you do Y ( make a Y as if you were doing the YMCA dance)

That's awesome. Isn't it amazing what students can come up with when they're given the opportunity and we don't bore them to death with long lecture. I love it when educators can share like this. I'll use this next week with my students. One thing to add. Another WBT Director (Jeff Battle) mentioned in another forum that it would be smart to link this directly with Scoreboard. Make sure the students are rewarded for their brilliant thinking.
