Seemingly related to a verse in "I'm Just Here To Get My Baby Out Of Jail," which in the DT. The following is Verse 4 of I'm Just Here to Get My Baby Out'a Jail from the Max Hunter Collection (with audio). There's a Grateful Dead version too (Click here):

I will pawn you my watch
I will pawn you my chain
I will pawn you my gold diamond ring
I will wash all your clothes
I will scrub all your floors
If that will get my baby out of jail

This is a floating verse, also used in "Nine Hundred Miles" ("I will pawn you my watch, / I will pawn you my chain / Pawn you my gold diamond ring"), which is in the DT too.
