Jeremiah and I are both fans of the Muppets. A few years ago I found a Kermit the Frog plush doll as a promotional sale item and I bought it for Jeremiah. It has graced the bookshelf in Isaac's room for a while now and Isaac lovingly refers to him as "Curtain."
This year for our anniversary I gave Jeremiah The Muppet Show: Season One on DVD - romantic, I know. Anyway here is the exchange I heard between Jeremiah and Isaac yesterday.
Isaac: Daddy, I want to watch The Muffet Show.
Jeremiah (trying to emphasize the correct pronunciation): The Muh-pet Show?
Isaac: Yeah, the Muffet Show.
Jeremiah: Say "Muh-pet."
So my little genius can do 100-piece puzzles right out of the box but is unble to say "Muppet."
