We all wear them every year, so why not test your knowledge of some of the most well-known ones that we've seen on the big screen?
'Tis the season for whipping on a Christmas jumper - and now that the majority of us are working from home, you might as well make a month of it.
Ahead of the annual Christmas jumper day this Friday, December 11 in aid of Focus Ireland, we thought we'd turn the day into a festive quiz to test your movie memory. Be warned however - not all of these movies are "Christmas movies".
And no, just in case the Kevin McCallister picture lulled you into a false state of easiness for this quiz as well, you will be tested to your Christmas jumper limits as you attempt to get all of the questions correct.
Best of luck, and let us know how well you do in the Facebook comments.
