Yanny v Laurel in top 10 trending YouTube videos of 2018
Think back to May and there was just one question which dominated the UK - can you hear Yanny or Laurel?
An audio clip went viral which divided the internet into two camps.
Now YouTube has revealed a video of the sound has made it into the top 10 most trending videos of 2018 in the UK.
Other videos on the list include Paul McCartney taking part in Carpool Karaoke - which came in at number one - and a live stream of the Duke and Duchess of Sussex's wedding.
Of course, we all love an animal video so it's not surprising a dog clip also made it into the top 10.
Ariana Grande, YouTuber David Dobrik and videos from Britain's Got Talent and America's Got Talent featured on the list as well.

British teen Courtney Hadwin walked onto the stage to audition for America's Got Talent looking nervous.
The judges - which included Mel B and Simon Cowell - were supposedly not prepared for what happened next.
Courtney, now 14, launched into an energetic performance of Hard To Handle by Otis Reading.
The crowd and the judges were wowed.
Simon said: "You were this shy little thing when you first came out. Then you sing and you're like a lion. Genuinely incredible."
Her performance earned her a place in the live finals after judge Howie Mandel pressed the golden buzzer.
She ended up coming sixth place in the grand final.
5. Yanny v Laurel video: Which name do you hear?

Chrissy Teigen said it was Laurel but Stephen King insisted it was Yanny.
And the difference in opinion was echoed across student halls, work offices and across social media back in May.
The secret, it turns out, is frequency.
The part of the sound that makes some people hear Yanny is higher frequency than that which makes some people hear Laurel.
Lars Riecke, assistant professor of audition and cognitive neuroscience at Maastricht University, said at the time: "If you remove all the low frequencies, you hear yanny. If you remove the high frequencies, you hear laurel.
"If your... ears emphasise both the higher and lower frequencies, you can toggle between the two sounds."
Turns out the recording is from vocabulary.com and guess what... it's saying Laurel.
