Fiery furnaces crazee

You see, Dr. Peter Pane was an interesting man,
and even more interesting doctor,
as he would use no material or remedy that wasn’t used in the manufacture of his doughnuts
[…]
Here in the doughnut factory,
they have confectioner’s sugar
so sweet it was caustic
and chocolate so bitter that it could kill typhus!
glazing so shiny,
it could set back glaucoma.
And filling so filling,
you didn’t need stiches!
