We’ve debated over the audio recording that read ‘Yanny or Laurel’, and whether the dress was blue and black or white and gold.
Now an unassuming image of a young girl in a park, donning a hair ribbon and a scarf, has sparked an online debate.
The image, which was shared on social media, got people talking when they noticed the size of her legs.
Can you see it?
The picture has been reposted dozens of times with many other users confessing they didn’t spot what was really going on until they’d read it in the comments.
If you look closely you’ll see the girl is holding a bag of popcorn that conveniently camouflages with the dried-out grass between her feet.
“I was seriously concerned and thinking, ‘this child needs to be saved and fed!’ and I saw someone yell out popcorn so I thought, ‘Well… Yes, we can feed her popcorn, but is it enough?’ and then I saw the popcorn bag,” said one Twitter user.
“I thought her legs were like that and was about to call you mean til I zoomed in and took another look,” another user commented.
Others claim they weren’t fooled by the illusion, saying “they got it right away”.
One man said his wife worked it out within 2.5 seconds, which he says is because “either she’s a genius or circle of trust is broken”.

This isn’t the first time that internet users have been left scratching their heads.
‘Is it a bird? Or is it a bunny?’
That was the question being asked by millions of social media users in August following this viral video.
The clip shows a bird with its beak in the air and a hand stroking its head.
When looked at from a different angle, the beak appears similar to bunny ears.
