Santa Clauses are coming to town.

Thousands of Kris Kringles and jolly Old St. Nicks are jamming streets, sidewalks and bars from on Saturday for annual SantaCon charity pub crawls.

In New York City, where temperatures hovered around freezing, the fermented merriment kicked off around 10 a.m. and was slated to stretch into the evening.

Santas 鈥� along with people dressed as Grinches, elves or other holiday characters 鈥� strolled to bars and clubs from midtown Manhattan to the East Village, flooding the streets with a crimson tide of Christmas cheer.

鈥淭he NYC SantaCon is a charitable, non-commercial, non-political, nonsensical Santa Claus convention that happens once a year to spread absurdist joy,鈥� the organizers鈥� website explained.

SantaCon participants are encouraged to donate $15 to enter participating venues. Organizers say the money will go to charity.

Similar Christmas-themed booze fests were being held Saturday in about 50 cities around the globe, including London, Phoenix, Winnipeg and San Francisco. Some placed held their SantaCons on Friday, last weekend or late last month. More are scheduled throughout December.

New York City police that open containers are prohibited in the streets and that blocking pedestrian and car traffic can lead to a summons. They also encouraged people attending the event to have a designated driver.

Commuter rail lines in the region banned passengers from drinking on board.
