Although Kieran Culkin isn’t a proponent for method acting, sometimes there’s just no competing with the real thing. Following a 2012 interview in which Mark Ruffalo revealed a “naughty young actor” once got him high on stage when switching a prop joint for the real thing during a play, the A Real Pain star confessed that he was behind the prank. “I was 17 and stupid,” Culkin told The Guardian of when he appeared in Playwrights Horizons‘ 2000 production of James Lapine‘s The Moment When.

With a bag of prop joints backstage, Culkin couldn’t resist the urge to switch one out. “Uh-oh. I believe it’s happened,” he said to himself weeks later as he smelled a familiar scent and “just watched” Ruffalo take a hit and pass to their co-star.

At intermission, Culkin had to come clean. “I’m like, ‘I thought this was a good prank. I’m stupid. Oh my God, I’m so sorry,'” he recalled. “But actually, they loved it.

Mark says, ‘I haven’t smoked pot in 10 years; the second half’s going to be so much fun.’ There was this other actor who had never smoked pot in her life.
