This is the physics version from The Physical Revue. The sheet gives the tune as Arthur Sullivan's If You Give Me Your Attention from Princess Ida; only Lehrer's replacement words are reproduced. The blackboard direction and the deliberately confused powers of x are part of the joke, not a lesson in mechanics. The separate mathematics version on page two is not spliced into these three complete stanzas.
If you give me your attention, I will tell you what I am
I'm a genius and a physicist (and something of a ham)
I have tried for numerous degrees, in fact, I've one of each
Of course that makes me eminently qualified to teach
I understand the subject matter thoroughly, it's true
And I can't see why it isn't all as obvious to you
My lectures all are masterpieces, excellently planned
Yet everybody tells me that I'm hard to understand
And I can't think why!
My diagrams are models of true art, you must agree
And my handwriting is famous for its legibility
When I write "gravitation" (scrawls on blackboard), say, or any other word
For anyone to say he cannot read it is absurd
My demonstrations all get more amazing every year
Though, frankly, what they go to prove is sometimes less than clear
And all my explanations are quite lucid, I am sure
Yet everybody tells me that my lectures are obscure
And I can't think why!
Consider, for example, oscillation of a spring
The force that acts upon it is a very simple thing
It's kx³ --- or kx² --- no, just kx, I'll bet
The sign in front is plus - or is it minus?, I forget
Well, anyway, there is a force, of that there is no doubt
All these problems are quite trivial if you only think them out
Yet people tell me, "I have memorized the whole term through
Everything you've told us, but the problems I can't do."
And I can't think why!
