On the latest episode of “Conan,” the host and his guest, Starlee Kine, attempt to do the impossible: figure out Jake Gyllenhaal’s height.

Kine is the host of “Mystery Show,” a podcast where — wait for it — she tries to solve mysteries. On a previous episode, Kine was tasked with figuring out Gyllenhaal’s height.

“There’s a whole website called CelebHeights.com, and there’s people who argue about how tall celebrities are, celebrities they’ve never met,” said Kine. “And this one, there were like pages and pages of people debating how tall Jake Gyllenhaal was.”

Kine said that she “took on the case” and brought Gyllenhaal into her studio, where he told her that he was 5 foot 11 and a half inches. Celeb Heights updated its “Jake Gyllenhaal” entry to reflect the star’s own height admission, but the website’s users refused to believe it.

To settle the argument once and for all, Conan surprised Kine and brought Gyllenhaal out to measure his height and end the crazy debates.

The verdict? After Gyhllenhaal takes off his shoes and flattens his coiffed hair, Conan says 5 foot 11 inches, and then says 5 foot 11 and a half inches. WTF? WILL WE EVER SOLVE THIS MYSTERY, JAKE?
