O Antiphon for December 24th

Latin:
O Tu es medium unum, Magister Grinch.
 Vos vere sunt calcaneum. 
Tute sicut GRATUS quasi cactus,
Tute sicut venustus ut anguilla.
Mr Grinch.

 English:
You're a mean one, Mr. Grinch.
You really are a heel.
You're as cuddly as a cactus,
You're as charming as an eel. Mr. Grinch.

 (Just Kidding, there really is no O Antiphon for December 24th, but I made you look!)
