YouTube Rewind 2014: An Amazing Mash-Up Video Of The Year's Biggest Viral Hits

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.
