He’s either saying he him self is God sent, or he’s a prophet and he’s referring to a third person.

He’s either on a mission like Jesus was or he’s a prophet like Isaiah and John (in the bible) telling the people to make a straight path for God (Jesus, which is God’s son sent on earth to teach a better way) he’s comparing him self to those biblical figures.

Isaiah 40:3 – In the wilderness prepare the way for the LORD; make straight in the desert a highway for our God.

John 1:23 – John replied in the words of Isaiah the prophet, “I am the voice of one calling in the wilderness, ‘Make straight the way for the Lord.’”

The obvious rhyme with run is cum, but it gets cut off by Bolton. Great Day Madvillain reminiscent. If you listen closely enough, you can actually hear him under Michael Bolton.

Michael Bolton was originally hesitant to work with The Lonely Island because of their vulgarness.

You want to work with guys like this. But at the same time I get invitations to perform at the Vatican! [Laughs] It could be potentially uncomfortable. And in the first few approaches some of the language was just so intense and off-color.

Bolton cutting off Andy before he can say “cum” could be a reference to that.

The narrator juxtaposes The University of Alabama’s Crimson Tide football team to represent the American winning attitude to that of his own sensibilities. Losing, or living a life of hedonistic pleasures and playing music for a living is winning to him. The name he has chosen, which, in his mind conveys a certain power is Deacon Blues.

Donald Fagen:

Walter and I had been working on that song at a house in Malibu. I played him that line, and he said, ‘You mean it’s like, ‘They call these cracker a–holes this grandiose name like the Crimson Tide, and I’m this loser, so they call me this other grandiose name, Deacon Blues?’

This line is very ambiguous in meaning.

The most clear answer is that the snitch has been poisoned with or is purposefully drinking the cleaning product Drano and the last things he sees are hallucinations. The repetitive slurring when he says “rainbows” signifies the intoxication. Rats are also associated living in sewage thus drinking Drano.

Also, taking the persona of a comic book villain, DOOM could be making a connection to DC’s Watchmen comic, one where a character named Rorschach’s mother dies by forced digestion of Drano by her pimp.

Another theory of the line could be that the hallucination he experiences from drinking Drano causes him to see rainbows coming out of a literal rat’s winking asshole. He’s so gone from the stuff that he sees things that are universally agreed upon as irredeemably repulsive, with a sort of silver lining (the rainbow). These lines illustrate the snitch’s overwhelming paranoia by describing the level of delusion he needs to achieve to get through the day. It also serves as an allegory towards how the snitch feels about himself. Assuming that the rat also refers to him, he drinks Drano in an attempt to recall any semblance of self-esteem he may have had in himself.

Killing is a force that has always been used for fun, hunting glorifies pain, and pain is made into a tribal, pagan god.
