Just noticed while watching this episode that after Jack sees Larry kiss Bunny, he dashes down out of the window to confront them. After he opens the door to go down the stairs, it appears a stagehand was visible on the right side. Anyone else notice this?

Yes, I saw it, too! Took a couple of views, but I finally saw what you were talking about. The stagehand was at the right side of the door, not the screen. Good catch!
