Republican presidential candidate Ben Carson revealed in a recent interview that he was an angry, violent teenager. For instance, he once tried to stabbed a friend with a knife when he was 14 years-old.

“As a teenager, I would go after people with rocks, and bricks, and baseball bats, and hammers,” he said. “Of course, many people know the story when I was 14 and I tried to stab someone.”

Just a reminder, Carson, who tried to stab someone, is running for president. Let that one sink in.
