It's hard to believe that this was literally the first time that Daffy Duck ever appeared in a cartoon, but it's the truth. Porky Pig plays a hunter going out to shoot a duck (he has to go out; he antagonized the man upstairs after accidentally firing the gun). Needless to say, while hunting, he comes across Daffy, and the latter can't get shot. After a weird snafu, Porky has to go (and by "go", I mean "run") back home.
"Porky's Duck Hunt" seems pretty low-brow compared to later cartoons, but if nothing else, it's good as a historical reference. When I was really young and watched a lot of the Looney Tunes cartoons, I always wondered why Porky Pig and Bugs Bunny never co-starred.
