The announcer at the Motherboy event tries to distract everyone from the fact that Buster has just crashed onto the stage after getting his hook stuck in a sandbag by letting the boys choose their own dance partners. In one scene it shows the young boys dancing with the mothers, but just before the commercial break it changes to full grown adults dancing with each other.
When Lucille's zipper (shown unzipped) is closed by Michael in the beginning, it was already closed prior to it even though it should not have been.
When Buster is zip lining across the hotel, the end of the zip line can be seen at the bottom of the balcony, much lower than the window. After the hook is let go by Buster, it crashes through the middle of the window, even though the end of the line would be much too low to crash through the middle of the window.
When Buster falls through the skylight and leaves his hook on the zip line, his left hand is clearly visible.
At 4:11 into this episode, a crew member is visible on the left side of the frame. He is holding a camera and filming perpendicularly to the angle at which we are viewing.
During the scene in the attic where Michael expresses his concern about the risk of keeping his father in hiding, a man holding a video camera appears on the left side of the screen very briefly. This mistake occurs at around the 4:11 time mark.
