Since you had 2 kids and I've got 3, I'll add the other good one I roll out every now and then. It was given to me by a co-worker just a few years older than me at the time (I guess he still is): when you go from 2 kids to 3, you switch from a Man-to-Man defense to a Zone. I thought it was funny at the time, afterward I learned it was dead serious.
