Poetry is where you find it

Someone wrote a book on the unintended poetry of Donald Rumsfeld. There is unintended poetry in the Combined Federal Regulations, too. This one is entitled, "Prohibited Threads" -- I've reformatted it slightly to for reading purposes:

Prohibited threads

Cotton thread,

and monofilament thread

of any composition,

will not be accepted

for use

in structural applications

unless demonstrated

to the Commandant

to be equivalent

to standard thread

in durability

in all foreseeable

conditions of use

and stowage.

46 CFR Ch. 1 Sub 164.023-5,

“Thread for Personal Floatation Devices: Performance; standard thread”

(10-1-04 edition)

A later couplet rings with hidden meaning:

Each thread

which complies

with all of the requirements

of a specification listed in table 164.023–5(a)

is assigned Use Codes

1, 2, 3, 4BC, 4RB, and 5 (any).

Got to dig the "5 (any) " conceit.

Really, is there a Use Code 5(any) to be aware of? And did it come out in the floor debate in the House?
