LONDON -- Once you've seen the shape in the cloud formation pictured above, you won't be able to unsee it.
Photographer Ceri Oakes took to Twitter on Tuesday morning to share a photo of some nacreous clouds taken in North Yorkshire, UK -- but the picture ended up capturing people's attention for different reasons.
The photo was taken by Oakes' future mother-in-law and it all looks innocent enough at first glance.

Upon closer inspection, though, it appeared there were certain shapes that stood out among the colours.
@CeriOakes there is a willie in that. Can you see it — trev (@trev0272) February 2, 2016
Yep. It's there alright.

In case you didn't spot it the first time around, here's a subtle hint.
