Jamie Dornan shares his unusual hobby with fans on "SNL" UK

The Down actor was hosting the latest episode of "Saturday Night Live UK" when he made the confession during his opening monologue.

Jamie, stepping in as host for the second episode of the British "SNL" adaptation, delivered the line with such earnestness that many in the live studio audience and those watching clips online were left wondering whether it was a comedic bit or an authentic admission.

"This isn’t a joke. God knows, I wish it was," he told the crowd as he revealed he collects rocks that resemble potatoes.

"Look at these gorgeous little things," he said, "And no, this isn’t a joke. God knows, I wish it was."

Jamie went on to encourage people to Google it to double-check that he was telling the truth.

"Seriously, this is who you want to sleep with?" he wondered.

Social media reactions were swift and amused. Clips of the moment circulated on Twitter and Reddit shortly after the episode aired, with fans sharing screenshots and debating whether the potato‑rock obsession was real or just good absurdist comedy.

Several commenters referenced the 'potato rocks' bit, with one admitting they "had to google it" afterwards because it seemed so unexpected.

Elsewhere, the 43-year-old featured in some of the sketches, and won the viewers over with his comedic acting.

One such sketch saw Jamie playing a father, and his daughter is ensuring he turns the clocks forward before it’s too late.

"The Time Man" is said to travel around the world to ensure everyone has fixed their clocks accordingly, with Jamie noting he will "imprison our souls" if a clock is out of place.
