Dubliners will be able to travel on the Luas for free this Sunday, as long as they're wearing a Christmas jumper.
It's to encourage people to take part in a World Record attempt for the most people with Christmas jumpers on gathered in the one place.
The challenge will take place on O'Connell Street this Sunday from 4.00pm.
It's beginning to feel a lot like Christmas!
