6. Scarface
The Original Line: Where did you get that beauty scar tough-guy, eating p*ssy?
The Ridiculous Redub... I'll openly admit that the original line relating to Tony's scar makes no sense - the last time I checked, that sort of behaviour didn't traditionally lead to open facial wounds - but the decision to replace the offending food-stuff with something as carelessly mundane, but circumstantially ludicrous as pineapple really takes the biscuit. Scarface is actually something of a seasoned professional when it comes to the artful redub: thanks to the film's gleeful violence and a potty mouth like no other, and there are a number of infamous re-edits that replaced the hard-hitting grit of the original with a diluted profanity and lessened violence that made no sense in some places, and added a frankly ingenious comical edge to some of the most famous scenes...
5. Old School
The Original Line: Cock... balls.
The Ridiculous Redub: Cotton balls. Taken from a scene in which Vince Vaughn's charismatic anti-hero mentor-type explains that he's introduced a system with his son to protect him from hearing anything inappropriate (by saying "earmuffs" to have him cover his ears), this re-edit makes zero sense in the context of its scene. Significantly cleaning up the words Vaughn uses to show that his son can't hear, the edit improbably turns Frank The Tank's hilarious interjections into the lunatic ravings of a man who has no grasp on reality. Quite why he would think "cotton balls" was an inappropriate thing to say to a child, or why he is subsequently berated by Vaughn's put-out father is just baffling.
