I noticed on my DVD in Part 2 of "The Boyfriend", Just after Kramer picks up the baby, it goes to the next scene and we hear a loud scream that sounds like it's from George. Even on the commentary, Julia says "What's that yell?" and nobody really elaborates on it. The "Notes About Nothing" says it is coming from Michael Richards at the idea of Kramer holding the baby. Is this a mistake or something?
