"If a woodchuck could... (tongue twisters)" joke

We all knew part of this as kids, but I never knew the whole thing...
If a woodchuck could chuck wood,
How much wood would a woodchuck chuck,
If a woodchuck could chuck wood?
He would chuck, he would, as much as he could,
If a woodchuck could chuck wood.
Can you imagine an imaginary menagerie manager imagining managing an imaginary menagerie?
Ned Nott was shot and Sam shott was not.
So it is better to be Shott than Nott.
Some say Nott was not shot.
But Shott says he shot Nott.
Either the shot Shott shot at Nott was not shot, or Nott was shot.
If the shot Shott shot shot Nott, Nott was shot.
But if the shot Shott shot shot Shott, then Shott was shot, not Nott.
However, the shot Shott shot shot not Shott, but Not.
