TV prints usually remove the line, "What an Eskimo pie-head!" At least one version of this cartoon removes Bugs's remark that, because a day is six months long at the South Pole, Bugs won't have to return to work until July 1953. (When the cartoon aired on "The Bugs Bunny Show" in 1965, the line was dubbed over with a new line where he says he won't have to return to work until July 1968.)
According to IMDb trivia the cartoon itself has largely disappeared from the airwaves because of the way it depicts the Eskimo villain. In other words, he's a laughable character, like all the other Bugs Bunny villains.
