If Nicholas Lyndhurst or David Jason had laughed when the chandelier fell, they would have lost the episode (they could only have one take and it cost them £6,000).
Edit
The chandelier incident actually happened to John Sullivan's (the writer) father in the 1930's - he always said it wasn't funny but after the episode aired he admitted it was.
