We’ve all been there, you’re on the Tube home - maybe you’ve had a couple of pints - and you can’t quite get your head around what you’re actually seeing.
That’s what happened to one commuter while he was travelling on the Piccadilly Line last week.
Reddit user lolihill posted the following image on Reddit on Thursday:
And all sorts of confusion ensued.
User karma-toes said: “That took me a good 25 seconds to see.”
SylvesterMarkus added: “Same. For the first 15 seconds I was convinced the mirror image was planted there.”
Soulteepee was similarly confused: “I thought it was twins, one dressed as a woman.”
Lolihull told the Evening Standard that they had to do a double-take when they first saw the sight.

The 28-year-old added: "My reaction was to take a picture to show my friends - they thought it was funny and encouraged me to post it on Reddit.
"[The man and woman] were sitting next to each other and I had the glass partition next to me and that caused the reflection of his head onto her body."
