Chris O’Dowd has noticed something very curious about Donald Trump.

The “IT Crowd” alum was on “The Late Late Show with James Corden” on Thursday night and talked about how, recently, he and his wife went for their green-card interviews and saw pictures of the U.S. president plastered everywhere.

“It’s a lot,” O’Dowd said. “And I’m not saying he’s not a handsome man, of course, but he’s very smiley in the photos.”

That’s when something occurred to him. “I hadn’t thought about it until I saw these extraordinary smiling photos that look like they were taken on McDonald’s Day at the White House but it occurred to me that I’ve never heard him laugh.”

Corden agreed: “I’ve seen him think something’s funny,” but not actually laugh out loud.

“I can only presume he’s not familiar with my work,” O’Dowd joked.

O’Dowd then did his impression of what he thinks Trump’s laugh must sound like. Take a listen.
