T.C.B.Y. is a national chain of frozen yogurt / ice cream shops. It's nothing special, at least for me, but you've got to see this. They have something they call "Rainbow Cream". It's vanilla ice cream with a TON OF FOOD COLORING!!!! Of course kids love it. I tried it and it was fine BUT, the next 3 times I when #2 I colored the water quite a dark shade of blue.
