"The Twelve Lays of Christmas"
...a song parody by Actaeon 

(Sung to the tune of "The Twelve Days of Christmas" by somebody-or-other. Posted December 24, 1996.)

For the twelfth lay of Christmas, my zoo love gave to me:

Twelve mares a-winking,
Eleven llamas licking,
Ten German Shepherds,
Nine wolves a-humping,
Eight elk a-bugling,
Seven Holstein heifers,
Six sheep a-swooning,
Five golden retrievers,
Four thoroughbreds,
Three Great Danes,
Two Brahma bulls,
And a stallion who really loves me.

Mare-y Kiss-Moose and an Appy Zoo Deer! :)
