The exact quote in at least one version of the musical was --
“Money, pardon the expression, is like manure. It's not worth a thing unless it's spread around, encouraging young things to grow.” -- Dolly Levi in "Hello, Dolly!"
Since I have not yet read the original version or the rest of this one, I will throw some wild speculations around:
Spec 1 -- It is learned that Joseph has a younger brother -- additional paperwork needed.
Spec 2 -- It is learned that Joseph has a sister -- new complications to the plot.
Spec 3 -- "John" finds that DNA "evidence points to Kevin and Joseph being fourth cousins. Now he has a UK connection via bloodline.
Spec 4 -- Other.
