Santa Claus
Santa Claus, also known as Saint Nicholas, Kris Kringle, Father Christmas, or simply Santa, is a legendary figure originating in Western Christian culture who is said to bring gifts to the homes of well-behaved ("good" or "nice") children on Christmas Eve (24 December) and the early morning hours of Christmas Day (25 December). The modern Santa Claus grew out of traditions surrounding the historical Saint Nicholas (a fourth-century Greek bishop and gift-giver of Myra), the British figure of Father Christmas and the Dutch figure of "Sinterklaas" (himself also based on Saint Nicholas). Some maintain Santa Claus also absorbed elements of the Germanic god Wodan, who was associated with the pagan midwinter event of Yule and led the Wild Hunt, a ghostly procession through the sky.
Mickey's Once Upon a Christmas
Goofy and Max are mailing out a letter to Santa Claus. However, as soon as they get home, Pete, the neighbor, tells Max that Santa does not exist, predicting how he can't fly around the world in one night. Things get worse when Goofy poses as Santa for some kids and Max finds out that he tricked him. Goofy is determined to prove to Max that Santa does exist and even stays up all Christmas Eve to keep an eye out for him. But after a long time, and after mistaking a Beagle Boy (who was robbing Pete's house) for Santa and falling off the roof, Goofy gives up hope of Santa coming. Now, Max does everything that Goofy did to make his father happy, including posing as Santa. In the end, the real Santa actually comes and gives Max the gift he had asked for earlier (as well as blowing some snow on Pete's house when the cunning neighbor tries to flatter the legendary figure). When Max asks if Santa forgot Goofy's present, Goofy answers that, every year, he asks for the same thing and, every year, he always gets it: Max's happiness.
