Milk, Cows and an Address

In an attempt to make the girls think laterally, T1 mostly, I've been throwing random questions at them...
Mostly math questions for T1. She can do addition and multiplication quite well, but I don't know if she knows why or when to use them...Hence this exercise.
My most common application involves apples - adding them and dividing them for a said number of people.

Yesterday, I was following a book to ask questions and I tried to see if they remember something they had seen about a year or two ago in an episode of Little Einsteins.

So I asked, "What's Milky way?"
T1 said, "It's part of an address!!"
T2 Promptly answered, "What comes from cows, amma!!!"

Need I say more??
