This photo of a girl posing with the Chuckle Brothers created the most unfortunate optical illusion

"What is in her glass?!"

The internet has been doing a collective double take at this photo that has been doing the rounds.

Its like an obscene version of The Dress.

Yeah, that's her arm with her hair draped over it, not whatever your dirty mind was thinking.

The unfortunate photo was taken at an appearance by the Chuckle Brothers at the Prysm nightclub in Leeds and posted to the Voodoo Events Facebook page.

The photographer, Joe Brook, said that he didn’t notice the phallic effect until after it started going viral.

"I saw it on my friends timeline and was like, why do you have this on here and she said look at her arm. 48 hours later its all over the internet."

And the internet think it's gas.

Oh my God. The way they're pointing at it! I'm in tears. https://t.co/BQ3G8MVqQ6

No word on whether the poor girl has gotten over the trauma… Of meeting the Chuckle Brothers, that is.
