Dear Mr Rubik

pseudoramblings
Liner notesYou'll recognise this as a reworking of Dear Mr Dylan. The idea of a protest song from the point of view of a conspiracy theorist who thinks the Rubik's Cube is a scam tickled me.

Dear Mr Rubik, forgive my stream of invective
I recently scrambled one of your cubes and now it seems to be defective
Mr Rubik, I'm not the type to complain
But Mr Rubik one star: would not buy again.

Dear Mr Singmaster*David Singmaster, MathsJam regular until he died a few years ago, wrote probably the first book on how to solve the cube., I recently purchased your book
Read it from cover to cover, I'm afraid it's gobbledygook
Professor: I'm sure you have a fabulous brain
Singmaster: one star, would not read again.

Dear Mr JPerm*If you want to learn the cube from YouTube, JPerm is the channel to follow., I recently binged your YouTube
And all of its camera trickery while you pretend to solve the cube
If you claim to solve it, it's obvious you're cheating or lying
My cube's never been close to solved in nearly 50 years of trying
Mr JPerm, I don't know why you try to explain
Mr JPerm, thumbs down, would not watch again.

Dear Mr Zemdegs*Feliks Zemdegs was a speedcubing world champion., a career as a fraudster beckons
You really expect anyone to believe you can solve that thing in under four seconds?
Who do you think you're fooling? It's plain to see it cannot be done
The odds against you solving it are 45 quintillion to one
Mr Zemdegs, we can't have a villain at large,
Mr Zemdegs, the jury finds you guilty as charged.
