Continuity mistake: After Bugs has performed his shaving act on Elmer, Elmer picks up his gun and hat and there are cut marks on his face. But when Bugs appears as a temptress, the cut marks have disappeared.
Continuity mistake: When Elmer is chasing Bugs, he initially has a single-barrel shotgun. Later on in the cartoon it changes to a double-barrel shotgun, and when he is pursuing Bugs on barbers' chairs, it goes back to a single-barrel one.
Trivia: When we see Bugs massaging Elmer's head in time to the piano melody, his hands are drawn with five digits instead of the usual four, to match the hand of a piano player.
