Perfect!

My father invented pinhole camera
And I was told to perfect it
I punched 20 holes around my tit

My father invented platonic love
And he told me to perfect it
But fancied dove didn't help a bit

My father invented perversity
And told me how to perfect it
But alas, in the trinity, a casket

My father invented poetry
And the plebian dialectic
I'm yet to be told to perfect it!
