Saint Nicholas (sometimes called Santa Claus) had a pun on his name cited in 2006:
 
“Does Santa have any money?”
“No. That’s why they call him St. Nickeless!”
 
A pun went viral on Twitter on July 5, 2012:
 
“The patron saint of poverty is St. Nickeless.”
 
The pun probably originated on the website Pun of the Day.
 
 
Wikipedia: Saint Nicholas
Saint Nicholas (Greek: Ἅγιος Νικόλαος, Hagios Nikólaos, Latin: Sanctus Nicolaus); (15 March 270 – 6 December 343), also called Nikolaos of Myra, was a historic 4th-century Christian saint and Greek Bishop of Myra, in Asia Minor (modern-day Demre, Turkey). Because of the many miracles attributed to his intercession, he is also known as Nikolaos the Wonderworker (Νικόλαος ὁ Θαυματουργός, Nikolaos ho Thaumaturgos). His reputation evolved among the faithful, as was common for early Christian saints.
 
The historical Saint Nicholas is commemorated and revered among Anglican, Catholic, Lutheran, and Orthodox Christians. In addition, some Baptist, Methodist, Presbyterian, and Reformed churches have been named in honor of Saint Nicholas. Saint Nicholas is the patron saint of sailors, merchants, archers, repentant thieves, children, brewers, pawnbrokers and students in various cities and countries around Europe.

Santa is so Santa-mental that he sometimes spends all his money on the toys that he brings to children everywhere. At those times, he’s called St. Nickeless.
