UPDATE: A caller to Deminski and Doyle noted Jeff looks a whole lot like "Son of Sam" killer David Berkowitz when he takes his glasses off. We'll never unsee that. — Editor.

"The Late Show With Stephen Colbert" has been having a blast with this.

When it was announced that Hillary Clinton picked Tim Kaine as her running mate, writers on the show saw an uncanny resemblance to their post production supervisor Mark Spada. Mark is a Jersey guy from Glen Rock.

As is often the case, he couldn't see the resemblance that to everyone else was obvious.

He suddenly found himself in front of the camera in a recurring role playing the U.S. Senator from Virginia. Now he's even met his lookalike in person through the show.

Check out this clip of Stephen Colbert convincing people on the street they're meeting the real Tim Kaine. Nope, it's really just our own Jersey guy Mark Spada.

Do you bear an uncanny resemblance to someone? Does everyone else see it ... but you? Tell us in the comments below or Tweet us @NJ1015.
