On October 6, Twitter user MartyMula tweeted a simple photo of a woman - but it has got the internet in a tizzy.
People couldn't figure out whether it was a photo of someone's neck, or a woman with long hair flowing down her back.
The tweet has amassed over 70,000 likes and 30,000 retweets, and people are still puzzled.
Been staring for 5 minutes and if its not a neck Im stupid— Michael Arminas (@Michael_Arminas) October 7, 2018
But this case appears to be closed - the photo is, in fact, a depiction of a young woman's back, not neck.

Until next time, Twitter.
