The absolute most hilarious thing my daughter ever said was when she was around 2 years old. Myself, being a vegan, I wasn't crazy about the idea of her drinking cow's milk, so I tried one day to introduce her to almond milk. I told her "cow's milk is for baby cow's, not people, so I want you to try this almond milk and see if you like it". My little 2 year old answered back " is that what baby almonds drink?"
And by the way, she prefers cow's milk to this day.
