To "if you me your attention."
If you give me attention, I will tell you what I am.
I'm a brilliant math'matician - also of a ham.
I have tried for numerous degrees, in fact I've one of
Of course that makes me eminently to teach.
I the subject matter thoroughly, it's true,
And I can't see why it isn't all as to you.
Each lecture is a masterpiece, planned,
Yet tells me that I'm hard to understand,
And I think why.

My diagrams are models of true art, you agree,
And my handwriting is famous for legibility.

All these formulas are trivial if you only think out.
Yet students tell me, "i have memorized the whole through
Ev'rything you've told us, but the I can't do."
And I think why!
