Is Donald Trump just Stephen Colbert's former persona on steroids? Stephen Colbert seems to think so.

In an interview on Sunday, the "Late Show" host admitted to seeing some parallels between the bombastic character he played for a decade on Comedy Central and the current Republican front-runner.

"I'm not the first person to say this, but I completely agree that he's my old character with $10 billion," the former host of "The Colbert Report" told CBS's "Face the Nation." "He's completely playing on an emotional level and so beautifully. I mean it's one of the reasons why I just can't do that old character anymore because he's doing it better than I ever could. Because he's willing to drink his own Kool Aid."

It's a comparison that's been drawn before — even by Colbert himself. Just a few months ago, he had Trump on his show to see if Trump could tell the two apart based on quotes alone. But can you? Can you tell the difference between the two? Take our quiz to test your ability to distinguish Trump from Stephen Colbert's former character.
