A group of kids start off with the "Your mama.." BUT, this being a Kmart ad, and these being elementary school kids, the mama-insults are mama-high-fives. Like "Yo mama is like a cheese-plate, she saved so much cheddar on that outfit". and "Yo mama is so fiscally responsible she got all this on free layaway." What? Just go with it, because the kids are very well cast. As is the rather strange gym teacher doing his stretches in blue gym shorts. Weirdness.
