Over the years I've seen and heard some remarkable things said by political candidates, but never have I ever witnessed an exchange like this with a presidential candidate.

JANSING: Is he the one you tried to knife?

CARSON: I'm not giving any information about who the person was that I tried to knife.

A candidate that's at the top of the GOP presidential primary polls is discussing who he may or may not have wanted to knife. Really? This has got to be a Dan Harmon skit, right?

I would have loved to see the late Richard Pryor do a skit on that one.

In case you missed it earlier, here's some back story from CBS on Carson's violent tendencies:

"I have plenty of energy. But, you know, I am soft-spoken. I do have a tendency to be relaxed. I wasn't always like that. There was a time when I was, you know, very volatile," Carson told NBC News. "But, you know, I changed."

The retired neurosurgeon went on to explain that "as a teenager, I would go after people with rocks, and bricks, and baseball bats, and hammers." He also spoke about the time, at 14 years old, when he "tried to stab someone" -- a well-known story of Carson attacking a friend during an argument over preferred radio stations. He missed: the knife hit the teenager's belt buckle and snapped.

Donald Trump had this to say about the knifing incident on CNN:

"It's a lot of things," he continued. "You know, when you say hitting your mother over the head with a hammer, when you talk about hitting a friend in the face with a lock, a padlock. And you talk about stabbing someone and it got stopped by a belt buckle."

Trump observed that "belt buckles don't really stop stabbings. They turn and twist and things slide off them. It's pretty luck if that happened."
