Continuity mistake: During the food fight Terry and Jenny are sitting next to another couple. Jenny's arms are by her side - the man puts a jelly down the front of his wife's dress, causing Terry and Jenny to laugh in the close up shot. The angle changes to a long shot - Terry has a straight face and Jenny's left arm is now on the table near a glass of wine that wasn't in the close up shot.
Visible crew/equipment: When Mr Muffet is hit in the face with a cream pie during the food fight finale, look at the top right hand corner of the screen and you can see the arm of a crew member throwing the pie at him.
