On ABC, several scenes were removed, including both times in which Daffy gets struck on the head by Granny's umbrella when he complains about Bugs being honored instead of him, the scene from "Buccaneer Bunny" (in which Yosemite Sam gets blasted at point-blank range by the cannons on his pirate ship), Elmer and Sam placing a bomb in the gift package to give to Bugs, and the ending of the cartoon, with Daffy as the ultimate victim of the bomb.
On the syndicated Merrie Melodies Show, only the aforementioned clip from "Buccaneer Bunny" was shortened.
