"...and a dog with lepto in its pee."

I saw this video over at the Worms & Germs blog.  It's a new take on a popular Christmas carol.  Enjoy!

Lyrics
On the twelfth day of Christmas my true love gave to me,
Twelve tubs of Purell,
Eleven raccoon roundworms,
Ten cats-a-scratching
Nine hungry hookworms,
Eight dogs-a-biting,
Seven cats with ringworm,
Six big fat dog ticks,
Five cats with fleas.
Four rats with cowpox.
Three tapeworms,
Two toxic turtles,
And a dog with lepto in its pee.
