It's the most wonderful time of the year; the ATP has released it's annual holiday video starring the likes of Andy Murray, Roger Federer, Jack Sock and many more, making slight fools of themselves in good spirits.

The pros don their best holiday sweaters and accessories (take a look at those festive shades), and then attempt to sing a tennis-themed version of "Jingle Bells."

Lines include "I'll go on vacation, maybe head out west," and "We’ll give you our best tennis and good reason to cheer."

The clip features Sock, Milos Raonic, Andy and Jamie Murray, Karen Khachanov, Dominic Thiem, Marin Cilic, Marcos Baghdatis, John Isner, Jean-Julien Rojer, Horia Tecau, Steve Johnson, Bob and Mike Bryan, Kei Nishikori, Henri Kontinen and John Peers.

There's also special messages from Federer and Rafael Nadal.

Watching this video on repeat is one great way to kick off your holiday season.
