Zoo

1. One day I went out to the Zoo,
   For I "wanted to see the old Gnu.
   But the old Gnu was dead,
   And the new Gnu, they said,
   Surely knew as a Gnu he was new.

2. A cheerful old bear at the Zoo
   Could always find something to do.
   When it bored him, you know,
   To walk to and fro,
   He reversed it, and walked fro and to.
