4-fingered cartoon characters, Why?

Which reminds me–if I remember correctly, on the Simpsons Homer one time made the comment that a newborn had all four fingers and toes, yet in another episode one of the bullies makes what I consider an inappropriate comment, for their universe, that stealing is a “five finger discount”.

I looked it up on snpp.com and apparently it was five finger in “The Telltale Head” but four finger discount in “Marge Be Not Proud.”

There’s also this reference in The Simpsons:

Marge Well I think it’s wonderful that your father has fallen in love with my mother.
Homer Well I’m opposed to the whole thing. Damn opposed!
Bart He’s damn opposed. Damn, damn, damn opposed!
Marge Bart! Homer, what possible reason could you have against Grampa being in love?
Homer If he marries your mother, Marge, we’ll be brother and sister. And then our kids…they’ll be horrible freaks with pink skin, no overbites, and five fingers on each hand!
