Are you old enough to remember Home delivery Milk?

I do, 

not this first thing below though..

I remember me and my brother racing to get to the milk first, the first to pull up that tab and pop that cardboard stopper off got to steal all the cream off the top for our cereal. My mother would have a fit. The idea was suppose to be that you shook the bottle and mixed the cream (Homogenized, what's that?)
