Quackodile Tears (1962)

Continuity mistake: When Daffy paints a hand grenade white to throw at the crocodile, he leaves a tin of paint by the nest containing the real egg. But when Daffy's wife puts him on the nest after the hand grenade blows up, the paint is nowhere to be seen.

Trivia: Daffy Duck doesn't have a white ring around his neck in this cartoon.
