Mark Ruffalo & More React to Chris Evans Accidentally Sharing Penis Pic on Instagram

Chris Evans caused quite a stir on social media Saturday afternoon when he briefly and accidentally shared a penis pic saved to his iPhone camera roll on his Instagram Stories. And his "Avengers" co-star Mark Ruffalo is giving the "Caption America" actor a hard time – as is the rest of the Internet.

Evans shared a short and innocuous clip of himself friends playing Heads Up. The video was a recording from his phone, which briefly shows his camera roll. But eagle-eyed fans noticed a black-and-white shadowy photo of a penis in Evans' collection... and so did Ruffalo.

Taking to Twitter, the "I Know This Much is True" star called out Evans and wrote:

Ruffalo wasn't the only one to react to the snap. Below find some of the best Twitter responses to Evans' blunder.
