I've wondered about that too, darling. I always waited, in vain, for a scene where the coffin lid slowly began opening with one of those marvelously prolonged creaking sound effects, followed abruptly by the crash of the candelabra clattering to the ground. Cut to close-up of Barn peering over the lid and cursing "Oh, @#$&!"
Could be even funnier than that scene of Queen Victoria dropping the secret treaty at the beginning of "Young Sherlock Holmes" with Gene Wiilder.
