For the fifth year running, YouTube has released its festive round up of the most popular videos of the past 12 months.
2013's collection featured a host of YouTube celebrities parodying the year's biggest musical hits.
This year's edition features such big names as The VlogBrothers, Conchita Wurst, Jimmy Kimmel and those guys who made a dog look like a giant spider.
The mash-up includes a nod to the Ice Bucket Challenge and songs from Pharrell and Lil' Jon.
Bravo, YouTube. Thank you for another wonderful year of cat videos and cooking tutorials.
