In some TV prints, we don't see the moments when Elmer shoots Daffy. Instead, we see hear it over a still frame of Bugs, who is presumably observing the action. Then we cut back to Daffy with his beak out of whack.
In other TV prints, we don't see or hear the gunshots. We only see Daffy's blasted-off beak.
In other words, the timing, pace and comic effect is destroyed. All this mangling of a comic masterpiece is for the dubious purpose of sparing children the sight of cartoon gunfire blasting a cartoon duck. This great film should be shown often, as it is, and broadcasters should ignore the bleating of a very small but vocal group of scolds and prudes. (In some cases the broadcasters are only anticipating the complaints of the scolds and prudes, but never hear from them.)
