The Captain America star has been at the centre of one of the biggest online jokes of the year, thanks to an unfortunate photo.
At first the scene looks innocent enough, with the US actor seen cuddling up to his wife Susan.
However, in the corner of the picture there is something very suspect going on.
Robert’s dog seems to be having rather a good time while his head appears to be between a lady’s legs.
Lol.
As expected, people are freaking out at how funny the picture is.
Things began when TV presenter Jamie East tweeted the picture along with the caption: “WTF is Robert Downey Jr’s dog doing?”

The snap so far has 29,000 retweets and 43,000 likes.
His followers also decided to write back with their hilarious takes on what the pooch could have been up to.
One wrote: “He’s burying a bone!”
While another added: “Lmao, chowing down on some kibble.”
A third chimed in: “Well, doggy-style it appears.”
Memes also popped up of the snap, with one fan tweeting: “Fifty Shades Ruffer.”
A second posted a pic of a dog covering its eyes with the caption: “Wife is gonna kill me.”
Those jokers.
