Jimmy Kimmel and Guillermo find out which kids are really naughty or nice

Jimmy Kimmel has been trying to help Santa in his quest to find out which kids are naughty or nice for the past few years.

Well, Kimmel, with the help of his good buddy Guillermo, dressed as elves to once again interview children and find out  if they were really nice or if they deserve coal this Christmas season. It's not quite like when Santa asks kids if they've been good or not, Kimmel and Guillermo give these kids a very thorough investigation.

Watch the hilarious interviews and answers these kids give in the video above.
