Who are RedBelly parodying in Borderlands: The Pre-Sequel?

RedBelly remind me so much of another two set of characters with a very similar repertoire, but I can't for the life of me place a name. I assume I'm thinking of some sort of '50s commentators.

I have read the Borderlands wiki, which mentions that RedBelly is a play on Ned Kelly, who lived from 1854-1880, long before radio was even invented. Secondly, Ned Kelly is a single person, who can't be the basis of a parody by two individuals (unless he had disassociative identity disorder).

Attributes of Red:

• Either isn't very bright or doesn't want to fight, seen when he says, "tea?" And Belly has to respond "No, death!".

Attributes of Belly:

• The more rational of the two. Tends to set the tone for both of them.
• The only time he says something like Red is on an ECHO device when he says, "Red and Belly sitting in a tree. K-I-S-S... wait, that's weird."

It is definitely a reference to Ned Kelly, who built a suit of armor that is very similar in appearance to RedBelly's armor..

They also appear to be a reference to Master Blaster from Mad Max Beyond Thunderdome. They also were a combination of the tiny smart character teamed up with a large dumb character.
