Sap

One holiday
As I fixed yams
To eat with Christmas
Goose and hams,
My boy Otis,
Little man,
Sat on my
Potato pan.
I thought, pretending not to notice,
Sit on a potato pan, Otis.

Said son Otis
On his pan,
"Daddy is
A silly man.
He loves this
Palindromic crap,
And I love him, but
Pa's a sap."
                              
                                  (Also painful: Pass sap.)
