Yes, today is the Feast Day of St. Nichols (St Nick, late of Santa Claus fame).

My favorite story about the real St. Nicholas:
Nicholas was the Bishop of Myra and attended the Council of Nicea in 325. One of the big debates at Nicea concerned the identity of Christ (was he fully divine or a creature). Arius taught that Christ was a mere creature, and was called upon at the council to argue his position. Apparently jolly old Bishop Nicholas could not endure hearing Arius’ heretical teachings and so marched over to Arius and slugged him.
