Continuity mistake: When Elmer Fudd goes to sleep on his hammock, Bugs Bunny paints his sunglasses black and you can see the time he sets the alarm clock to go off reads 12.00. But when Elmer picks up the alarm clock, the time on the clock now reads 11.55.
Continuity mistake: When Elmer 'plays dead' with the grizzly bear, he lies down and you can see his hat is beside his head, but when Bugs (pretending to be a bear) kisses Elmer, the hat has disappeared.
Continuity mistake: When Bugs is painting Elmer's glasses with black paint, you can see there is only an alarm clock on the table next to him, but when Elmer thinks it's night time, look at the table and a torch has suddenly appeared.
Continuity mistake: When Elmer puts up his tent at the park, you can see there is a deckchair next to the tent, but when Bugs pulls the tent into his hole in the next shot, the deckchair has disappeared.
