Reading "The Night Before Christmas" and we got to the line about Santa having a cherry nose:
Liam: I thought he had a carrot nose
Me: no that's a snowmen
Liam: oh.
Molly: what kind of nose do I have?
Liam: a plum!
Me: what kind of nose does your Dad have?
Liam: a pineapple!
And according to Liam the following people do not celebrate Christmas: the police, people who live in the desert, and anyone with a poisonous green hand.
