No one could ever accuse Chris Pratt of taking himself too seriously.

The Passengers star showed off his self-deprecating humor on Instagram this week, posting pics from his recent Vanity Fair photoshoot along with his own joke commentary.

In a post shared Thursday, the actor gave a comical backstory behind one photo in which he stares off into the distance while standing between two stones.

"I have to credit the brilliant photographer @markseliger who discovered me wedged between these two rocks," Pratt joked. "It took him all day to pull me out. I had been stuck there for hours. I had barely enough strength to stare pensively into the distance. I mean, it was bad. Anyways, I almost had to chew off the lower half of my body to get out. But I'm not flexible enough. Bottom line, I could have died. But thanks to the brilliant photographer @markseliger I'm alive to tell the story, which is currently being optioned for a movie."

In another shot, Pratt joked that while fans might have thought he was giving a sultry look to camera, what he was actually doing was "casually sniffing [his] knuckles."

Last year, Pratt similarly mocked his photospread for In Style after being named the magazine's Man of Style.

"Full disclosure I did not pick out any of the clothes which is kinda funny for a guy who is called the 'man of style,'" he wrote at the time. "I mostly like T shirts with American flags on them. Usually I go for the one on the top of the 'shirt pile.'"

Inside the pages of Vanity Fair's February issue, the 37-year-old actor opens up about what his life was like before fame and stardom.

"I was selling coupons for things like oil changes or trips to a spa. I was great at that," he tells the mag, noting the gig helped prepare him for getting rejected for acting roles later in life. "That's why I believe in God and the divine. I feel like it was perfectly planned. People talk about rejection in Hollywood. I'm like, 'You're outta your f****n' mind. Did you ever have someone sic their dog on you at an audition?'"

Pratt's Vanity Fair issue is on newsstands now.
