When Megan tells Sean not to "put it all the way in," he takes a brief pause, takes a breath and closes his eyes. But the very next shots shows his eyes wide open, about to take another breath. Bad edit.
In this episode, the way the scenes are arranged make it seem like it's a little out of order. First, Will and Grace are running around trying to keep Naomi and Kai a secret from Rob and Ellen. Then, it cuts to Karen and Jack at the school where Karen enters the principal's office and Jack meets John. Next, we see Will and Grace with morning hangovers. Then, Jack and John are still talking as Karen is about done with her meeting. This would technically mean that Jack, Karen, and John would have spent the night at the school, which couldn't possibly be true.
Despite Will moving constantly as he moves, his blanket keeps changing positions on every camera angle.
When Debra and Sean burst through the Asian screen, Sean starts laughing so hard that Debra, who has landed on top of him, puts her hand over his mouth.

Eric McCormack(Will) and Debra Messing(Grace) appear together only in the opening scene and would not appear together again for the rest of the episode.

When Karen orders Ben's secretary to put a stamp on a letter and put it in the mail, there is no writing whatsoever on the envelope.
When Grace and Jack are showing their teapot, look in the background, A few of the people keep changing places depending on the camera shot.

The light shining onto the NYC backdrop makes a few of the buildings look flat. You can tell it's just a flat picture.
This is the first appearance of Will's dad, played by accomplished actor/director Sydney Pollack.
When Will looks out the window at his father parking, he says "He found a spot on 78th." 155 Riverside Drive is at the corner of Riverside and 88th Street. There is no way he could see his dad parking 10 blocks down the street.
