A Rubric on Rubik's Cubics

Respect your cube and keep it clean.
Lube your cube with Vaseline.
Beware the dreaded cubist's thumb,
The callused hand and fingers numb.
No borrower nor lender be.
Rude folk might switch two tabs on thee,
The most unkindest switch of all,
Into insolubility.
[Chorus] In-sol-u-bility.
The strangest place to be.
However you persist
Solutions don't exist.

(This poem is set to the tune "Ta-Ra-Ra-Boom-De-Aye" and was written by Claude Shannon)
