1 & 2

1 & 2 are two recurring background characters commonly used to fill the space or to represent a bigger picture.

They are two middle aged men, one black, one white. Both accompanied with mustaches and sunglasses. Their true names are unknown, but they are commonly seen doing odd jobs around town.

Employment
In "Offended", 1 & 2 were pretending to be a woman's set of easily entertained children (the only time they're seen without mustaches).

In "The African Adventure, pt. 2", the pair are two soldiers that come to rescue the guys and Kitty from the Somalian pirates.

In "Cody Can't Be Black", 2 is in blackface unbeknownst to 1 who is black and are there to criticize Cody when he lets the n word slip while rap battling MC Jackson.

In "The Few, The Proud, The Not-Cody", 1 & 2 reprise their roles as soldiers to complain about Cody being a part of the marines, ruining their fun.

In "The Gang Goes To The 60's", 1 & 2 are seen robbing a bank with no criminal charges against them whatsoever.

In "Sell Out", the pair are police officers trying to convince Kitty to not rob the bank only to be easily distracted and 2 asks 1 out on a date.

Personality
The two are very aware of one another and can read each other like a book. However, they are not of the most intelligence and are very commonly either distracted or frustrated.
