I now understand what Bob meant when he said

"Oh God said to abraham kill me a son
Abe said man you must be puttin me on
God said no, abe said what
God say you can do what you wanna but
The next time you see me comin you better run
Well abe said where dyou want this killin done
God said out on highway 61
Well georgia sam he had a bloody nose
Welfare department wouldnt give him no clothes
They asked poor howard where can I go
Howard said theres only one place I know
Sam said tell me quick man I got to run
Oh howard just pointed with his gun
And said that way down highway 61
Well mack the finger said to louie the king
i got 40 red white and blue shoestrings
And a thousand telephone that dont ring.
Do you know where I can get rid of these things?
And louie the king said let me think for a minute son
Then he said yes I think it can be easily done
Just take everything down to highway 61
Now the 5th daughter on the 12th night
Told the first father that things werent right
my complexion, she says, is much too white
He said come here and step into the light
He said hmm youre right let me tell the 2nd mother this has been done
But the 2nd mother was with the 7th son
And they were both out on highway 61
Now the roving gambler he was very bored
Trying to create a next world war
He found a promoter who nearly fell off the floor
He said i never engaged in this kind of thing before
But yes, i think it can be very easily done
Well just put some bleachers out in the sun
And have it on highway 61"
