I'm actually a really nice guy, and I'm not confrontational at all, but some situations require someone to stand up and say something (it doesn't have to be a threat, it just needs to sound threatening), and in 9/10 cases, the offender knows they are in the wrong, sees who they would be standing up against, and decided to not push their luck.
Ask Insanolord, he sat next to me at E3 2011.
and to answer your question, No, I haven't heard of that show, and no, I have never listened to any podcast.
