John: "Mommy, learned a new word today!"

Me: "That is exciting...what is it?"

John: "Con-cen-trate

(the hyphens represent pauses and each syllable was said with a head nod)

Me: "That is a big word! What does it mean?"

John: "Don't know"

Me: "Where did you learn it?"

John: "Elmo"

When he said Elmo, he said it in a way and a facial expression like "Elmo teaches everything so you should let me watch it all the time."
