'British' Beef
A throw-away line while Scrooge is listing the things that can upset his stomach, when he first encounters Marley's ghost.
This version was made while the Mad Cow/BSE scare was in full effect but it's a very jarring line that doesn't belong at all. Patrick Stewart as Executive Producer probably thought it was an amusing line at the time but it doesn't stand up well after just a few short years.
This is one of the best arguments for leaving topical jokes out of the classics - they don't age well.
