ON THE 12th DAY OF CHRISTMAS,
My true love gave to me.
Oops,
Maybe it was the 3rd day of Christmas?
Or was it the 5th?
Anyway.

On the who- knows -what -day of Christmas.
MY TRUE LOVE GAVE TO ME
A partridge in a pear tree.

No, wait.
Wrong again.
My true love gave to me
A Northern Mocking Bird
In a Mesquite tree.
Close enough
