Every time I am shopping with girls and we see some version of a common item that's smaller than usual, there's a definite excited reaction. Tiny saucepans, little boxes, micro-sized cake tins, it's all the same. This gives me an idea: the Tiny Little Cute Things Store, full of really little things for girls to love and men to loathe. It would sell basically everything you'd need in a house if you happened to be child-sized. No female would leave empty handed, and I'll make a killing!

PS - It would be a great place to shop for cubby houses.
PPS - Or play kitchens.
