"We need to tell Tony [worship leader at our church] to get some chicken for Skarloey's big day out [a Thomas the Train video we watch almost daily].", as he is pushing his train down the sidewalk.
"Mommy, I got the bugger. Here it is on my finger."
...and, our favorite:
"Daddy, are you my father?"
"Yes, I am your father."
"Mommy, daddy is my father!"
"And I am daddy's son!"
