Josh Brolin turned his recent appearance on The Late Show with Stephen Colbert into something far more than a routine interview.

What began as a standard late-night conversation quickly spiraled into comic chaos as the actor and the host leaned into their natural chemistry, creating one of the show’s most talked-about moments.

Brolin wasted no time breaking the usual format. At one point, he boldly slid into Colbert’s chair behind the desk, mimicking the host in a playful takeover.

The audience erupted in laughter as Brolin riffed with Colbert, who responded by tossing a splash of water at his guest to reclaim control of the show.

The hijinks didn’t end there. Brolin, known for his charismatic yet unpredictable personality, pretended to urinate on Colbert’s desk, escalating the bit into full-blown late-night absurdity.

Instead of shutting down the gag, Colbert leaned into it, feeding off the energy and allowing the segment to spiral in the best possible way.

Fans quickly took to social media to highlight the pair’s comedic timing and lighthearted banter, with many calling the interview one of the funniest they had seen in months.

While Brolin was originally on the show to promote his latest projects, the exchange underscored the lasting appeal of spontaneous, unscripted comedy in late-night television.

Instead of sticking to rehearsed talking points, Brolin and Colbert embraced unpredictability, and the result was a segment that had both the studio audience and viewers at home laughing along.

The lively interaction has since gone viral online, cementing Brolin and Colbert’s dynamic as one of the more memorable guest-host pairings on late-night TV in recent memory.
