frequently overheard at our house
Samuel: "Mommy, I love you forty two."
Me: "I love you forty five!"
Samuel: "I love you a hundred and a googolen*."
*One day I explained to the kids that there is no such thing as the biggest number, but a very large number is called a googol (which is a '1' with 100 zeros behind it). They frequently throw around this knowledge, but almost never get the word 'googol' right.
