When you think of the greatest Christmas song of all time, there are a few songs that come to mind instantly, 'All I Want For Christmas', 'Snoopy's Christmas' and 'Last Christmas'.
When you critically analyse every single Christmas song that was ever made, none of the three songs above make the number one spot.
It turns out that there is a very specific recipe that a song has to follow to be considered for this position.
"This channel in the UK, they went through 30 years of number one Christmas songs, and they figured out that there's a recipe to success," Jason said.
"Clearly not a busy time in the office," Bernie quipped.
Jason then revealed what the reported recipe was: "It has to have sleigh bells, children singing, church bells, harmony, and references to love."
After Helen incorrectly guessed 'Winter Wonderland' Jason revealed the correct answer: 'Mistletoe and Wine'.
In your opinion, what is the greatest Christmas song of all time?
