If you're the parent of a little kid, or if you happen to be a kid, you'll be well aware of the song 'Baby Shark'.
It's the tale of a family of sharks, and it's the viral hit of 2018, with more than 2 billion views on YouTube. It even cracked the UK top 40.
But it's actually been around for around seven years, though it took until 2018 for the brain-bleeding earworm from South Korean YouTube kids' channel PinkFong to take over the world.
In fact, according to Wikipedia, the concept behind the ear-meltingly annoying jingle actually originated in the 1900s before appearing in a video called "Kleiner Hai" in 2007.
In 2011 a song called 'Baby Shark' appeared on albums by the The Learning Station and Johnny Hall.
PinkFong released its own version in 2014 and it spread across Asia in 2017, eventually making its way to New Zealand today.
