For the past 10 years, the Avengers has been dominating the box office and with so much success on the screen, it has appeared to rub off on its own cast. The original six; Robert Downey Jr, Scarlett Johansson, Chris Hemsworth, Mark Ruffalo, Chris Evans, and Jeremy Renner have developed a close bond in real life.

Appearing on The Tonight Show starring Jimmy Fallon, Jeremy Renner shared the meaning of the group’s matching tattoos as well as letting it slip about a group text the team created.

“We’ve all been together over the past decade,” Renner told Jimmy Fallon of the core actors who pretty much changed movies forever. We’ve spent a lot of time together, have a lot of similar shared experiences in life.”

Like most groups of friends, Renner roasted Mark Ruffalo for “chickening out” of getting his tattoo. “I’m not sure why,” Renner said. “Get some henna! You got to get something. It’s not only about the tattoo, it’s about a celebration of our friendship that has bonded over the past decade.”

And what a friendship it is. Can we join?
