Continuity mistake: When Ala Bahma asks Bugs if he wants some blackberry pie, he produces a pie and pushes into Bugs' face. At this point, you can that the poster around the hole of Bugs' home in the tree has writing on it, but in the next shot when Bugs takes some pastry off his face, the writing has disappeared.
Bugs Bunny: Look, Doc. Do I go around nailing signs over your house? Do I? There's still such a thing as private property, you know. Did you ever hear about the inalienable right of the sanctity of the home?
