Plot: Buddy was a baby in an orphanage who stowed away in Santa's sack and ended up at the North Pole. Later, as an adult human who happened to be raised by elves, Santa allows him to go to New York City to find his birth father, Walter Hobbs. Hobbs, on Santa's naughty list for being a heartless jerk, had no idea that Buddy was even born. Buddy, meanwhile, experiences the delights of New York City (and human culture) as only an elf can. When Walter's relationship with Buddy interferes with his job, he is forced to reevaluate his priorities.
Alternative Plot: Buddy (Will Ferrell) was accidentally transported to the North Pole as a toddler and raised to adulthood among Santa's elves. Unable to shake the feeling that he doesn't fit in, the adult Buddy travels to New York, in full elf uniform, in search of his real father. As it happens, this is Walter Hobbs (James Caan), a cynical businessman. After a DNA test proves this, Walter reluctantly attempts to start a relationship with the childlike Buddy with increasingly chaotic results.
