This relic of Daffy Duck's brief angular period (his forehead looks like a right angle) doesn't carry a directorial credit, but I read that Frank Tashlin directed it. Anyway, it goes like this: a father gave his daughter a baby duck...who grew up to be the out-of-control Daffy, to the point where the father starts wanting to get rid of him. But not only is Daffy always a step or two ahead of the creep, the daughter loves Daffy no matter what he does!
This features Daffy in full manic form: he sits at the table laughing hysterically while telling jokes, and runs around at breakneck speed. No wonder the daughter likes him so much! Also, there's a brief reference to the recently ended World War II, as Daffy explains that the government doesn't want people taking unnecessary trips.
Anyway, "Nasty Quacks" is truly a look back at the days when Daffy's name actually referred to his personality, a few years before Chuck Jones turned him into a greedy narcissist*. Mostly just a way to pass time, but a really fun one at that.
*Don't get me wrong, Jones really did some great work with the vicious Daffy; part of the idea in the Hunting Trilogy is that Daffy tries to undermine Bugs Bunny's integrity, and so Bugs gets Elmer Fudd to shoot Daffy.
