Billfold Ballade

“What’s in your wallet?” asks Samuel L.
(‘Demands’ is more like: Sam's as huffy as hell.
He insists I acquire mega-augmented credit, 
then tells me he knows those from whom I must get it.) 

What’s in my wallet? I’ll clue you in, Jackson.

I’ll spit it out straight -- I’m no brother who backs in.

'Tain't minimum wages. 'Tain't lottery haul.

So: what’s in my wallet? 'Tain't nothin' at all.
