Stinky Sesame Street?

For some reason Violet got stuck on that phrase today.  She got stuck on the line "Cow is STRONG" from her In the Doghouse book.  She kept point to it and saying "Sesame Street is Stinky!"  And then she'll cackle madly.  She did this easily a dozen times before we coaxed her to the next page.  My favorite part is that the laughed even harder on the last "Stinky" as the first one.
