School Buds and the "Meat Pile"

I went over on Tuesday afternoon to his "school" (Child Care Center) and brought some of the cookies my Mom sent (Thanks Mom!) an we all had a snack and sang Happy Birthday to Jack. A couple of his buddies lined up for a picture and as always, it ends in a "meat-pile". That's when they all grab eachother and fall down in a pile. Its like wrestling, but there isn't any pinning of your opponent, actually, there aren't any opponents. Its just a meat-pile.
