Yellow Car!

I have been spending lots of time in the van, driving the boys to their various destinations.

A game they play is "Yellow Car"... is this a real game? The object is to see a yellow car and call out "YELLOW CAR" before the other sibling claim credit to it. A yellow punch buggy counts as 2 points.

Now this is the part I am sure they made up... after accumulating 10 points, you can punch someone 10 times or let your points add up and use them later. Hum...

So I have joined in playing the game. Apparently I am pretty good! :P I have 11 points or so in one day! How do I pick who is the lucky one to get punched?

Eeny, meeny, miny, moe?
