The photo, tweeted by Elle Bailey a couple of days ago, shows a woman with a rather long arm. "My sister's arm in this club photo looks about 6ft long I'm crying," Ms Bailey says in her tweet posted on May 1. Her picture has now gone crazy viral online with almost 20,000 'likes' and over 5,000 retweets.
Now either the woman photographed is a distant relative of Mister Fantastic or Elastigirl/Mrs Incredible or it's just a perfectly timed and angled picture.

Since being shared, the photo has got many people confused - some who can clearly see the illusion and others who cannot.
"Leave me to be the one to see this as a normal picture and not see the supposed long arm," says one commenter on Twitter. "That's crazy, took me a minute to figure out that the arm is from the girl on the left," says another.
