What is Yoohoo, Anyway?

Papa Salty just called to correct my spelling of Yoohoo - the milk of the south! The product placement in this photo was of no help to me as I tried to get the spelling right! Now I know......and to Lily's dismay, Yoohoo is not going to be a staple in our fridge. But she'll always have something to look forward to when we point it north to SGI.
