Continuity mistake: When Bugs reaches the top of the stairs in Bedlam Manor, Yosemite Sam (dressed in a suit of armour) tries to chop off Bugs' head with an axe, but Bugs ducks and Sam falls down the stairs. When we see Sam falling down the stairs in the next shot, Bugs has disappeared.
Continuity mistake: When Sam says "Salt? Why didn't you say so?" at the dinner table, you can see there is a knife next to his plate, but when he leaves his chair to take the salt shaker to Bugs, the knife has disappeared.
Continuity mistake: When Sam takes the salt shaker to Bugs, he places it on the corner of the table, but when Sam walks back to his chair, the shaker has disappeared.
