Copious amounts of alcohol were involved.

Oddly enough, even Wikipedia doesn't know.

Disney characters never have both parents. Most of the time they're raised by their uncle or aunt.

I think Walt Disney might have been a sad man.

The only characters with known mothers are the ducks. Donald's mother was Hortense Duck, the sister of Uncle Scrooge. Huey, Dewey and Louie's mother is Della Duck, Donald's sister. Their father is unknown, but I have my suspicions that it was Daffy Duck, but Donald wouldn't let his sister marry a duck of color.

Rodents of Unusual Size
I always thought this movie was underrated in the Disney cannon.

The answer is of course Goofy is parthenogenic and Max was the result of his once in a lifetime thigh budding. Max was initially a cellular test tube specimen, a partial clone with some genetic variation. No cartoon woman in her right mind would go near such a genetic freak.

Then how come Max is a young angry malcontent black man while Goofy is all aww shucks gee whizz massa?

My theory is that Max's conception was the result of Goofy's clumsy nature.

He somehow in the course of his pratfalls, managed to fall on top of and penetrate a random female passerby. He was quickly stuck with a paternity lawsuit and given full custody of his unholy spawn.

Fun fact: Max is the only character in the Disney canon that ages. While Huey, Dewy and Louie are perpetual schoolkids Max is now in his mid twenties.

Fun Fact 2: Were it not for Carl Barks Donald and his nephew's parentage would most likely have remained an enigma to this day

Don Rosa knows who Huey, Dewey and Louie's father is, but will never be allowed to reveal it. That's because their father is Daisy Duck's brother, which explains why they have the surname Duck when their mother would normally have lost her maiden name in marriage. The reason Disney have prevented this revelation from being shown in the comics is probably because this means that, oh horror of horrors, DONALD AND DAISY ARE RELATED BY MARRIAGE.

There was a late period Goofy cartoon, from the late 40s or early 50s, where Goofy had a wife and a son that was NOT Max (he had red hair). As I recall, she was out of his league.

If I look any further into this mystery, I will be sidling into the Furry Zone, and I'm not going to do that.

Rum Revenge
That, or possibly a parody of inferior Disney wannabes. Though it's most enjoyable as a self-parody.

Goofy Gorilla
Yes, that's the line. Possums are often portrayed as hanging from a limb by their tails. Though since it doesn't really happen, and the legend was perhaps a reference to lynching, I too am somewhat perturbed.

Spit Spingola
It is pretty depressing. Not as bad as Brave Little Toaster though.

Absolutely...can't remember exactly why, though. I guess I should watch it again?

Oh...I remember now =/

Is that why you guys broke up? Or were you already broken up?
