Nasty Quacks is a 1945 Warner Bros. cartoon in the Merrie Melodies series. It was the final Daffy Duck cartoon directed by Frank Tashlin, who is not credited as he had already left the studio for the second time (this time, for good). Voices of the male characters are performed by Mel Blanc.
The father of a suburban family buys a black duckling for his daughter, who dotes on the duck. The duck quickly grows up to become Daffy Duck, whose loud and obnoxious behavior is driving the man to distraction, but the daughter defends her pet at every turn.
The father then buys a white duckling for his daughter, who then changes her focus totally to the new duckling. The father comes at Daffy with murder in his eyes, and chases Daffy around the house. Daffy hides in the room where the duckling is being kept. He decides to kill the duckling, but has a pang of conscience and decides to make the duckling grow to adult size, and then kill him. Daffy pours vitamins down the duckling's throat. With a "bay-woop", the duckling instantly grows into adulthood - and turns out to be a shapely female duck. Daffy looks at the camera and shrugs his shoulders.
Cut to the father walking down the stairs, laughing to himself, thinking he has chased Daffy out of the house. He is stunned to see Daffy; the female; and several newly-born ducklings bouncing around the dinner table, as Daffy is launching into one of his raucous stories.
- At one point, Daffy packs up his things and announces that he's leaving, then comes back and tells his master that "...the government doesn't want us to do any non-essential traveling!" (a reference to how travel had to be reserved for WWII soldiers fighting overseas) after he comes back into the house. At the time the cartoon was released in theaters, World War II had ended.
- This was one of two cartoons shown on Cartoon Network's Looney Tunes marathon on New Years' Day 2009 to carry the a.a.p. logo, the other was another Daffy Duck outing - Daffy Duck in Hollywood. Most other a.a.p.-owned cartoons on the marathon were shown as "dubbed versions", and the rest that weren't did not bear the a.a.p. logo. The cartoon's "dubbed version" aired on the November 15, 2009 Looney Tunes marathon; however, another audio track was playing simultaneously with the cartoon (it is not known whether it was a foreign-language track of this cartoon or it was from a different cartoon altogether). This isn't to say that the a.a.p. version won't air in the future, as even into the 2000s, some cartoons were shown as an a.a.p. version and a "dubbed version".
