Succession star Kieran Culkin recently revealed an amusing anecdote about how he once pranked actor Mark Ruffalo by getting him ‘high’ during their time together in a stage production. This revelation has piqued the interest of fans eager to uncover the amusing details surrounding this light-hearted incident.

Here’s a deeper look at Culkin’s hilarious prank involving Ruffalo.

How Kieran Culkin Hilariously Pranked Mark Ruffalo by Switching His Prop Joint with a Real One

Kieran Culkin disclosed that he executed a playful prank on Mark Ruffalo by swapping a prop joint with a genuine one, resulting in an unexpected high for Ruffalo. This mischievous act took place when Culkin was just 17 years old, while they both starred in the stage production The Moment When in 2000. This incident showcases the youthful exuberance and spontaneity that often accompanies early careers in the entertainment industry.

In a recent interview with The Guardian, Culkin reminisced about this hilarious prank, admitting, “I was 17 and stupid.” He vividly recounted observing Ruffalo passing what he believed to be the fake joint to another co-star, reflecting on how he thought it was a clever prank at the time. This lighthearted confession reveals the innocence often found in youthful mischief.

“I’m stupid. Oh my God, I’m so sorry,” Culkin remarked, recognizing the folly of his actions in hindsight. He further shared that both Ruffalo and their other co-star enjoyed the real joint, with Ruffalo notably mentioning that he hadn’t indulged in such a way for a decade. “And then Phyllis Newman comes in and goes, ‘I haven’t smoked pot since the 1960s. Thank you, darling,’” Culkin recalled, adding a touch of nostalgic humor to the story.

Kieran Culkin also mentioned that their stage manager was mildly upset about the prank and ultimately confiscated the joint. He humorously recalled a time he joked with Colin Hanks about repeating this prank during their performance of This Is Our Youth in London, to which Hanks jokingly threatened to “punch [him] in the face.” This playful banter illustrates the camaraderie and humor that often exists among actors during productions.

In a further amusing anecdote, Culkin shared how he once handed Hanks a real joint while on stage, resulting in Hanks’ excited yet nervous reaction, which caused the joint to crumble when he attempted to light it. This moment reveals the unpredictability and hilarity that can ensue during live performances, adding to the rich tapestry of theatrical experiences.

Mark Ruffalo had previously shared his own perspective on this amusing prank during an appearance on The Graham Norton Show in 2020. However, he humorously chose to keep Culkin’s identity under wraps, referring to him only as a “very naughty young actor,” adding an element of mystery to the story.
