He's been on C2C a number of times in the past, including I think in the past couple years. Seems like he was usually on with Knapp who never challenges his UFO/woo guests. Last night it was obvious he held Connie in utter contempt. I think it was her trying to apples-to-apples compare her work on QVC with developing new technology.
Your reference to QVC piqued my interest and I gleaned over a few videos of her on YouTube hocking garbage products on QVC. She supposedly has a culinary degree yet she does everything you are not supposed to do in cooking. But, whatever. She was getting money for those infomercials so, hey more power to her.
I also came across her doing sports commentary for international volley ball.
I didn't want to go further down that rabbit hole so I just exited.
Anyway, I don't recall hearing that guest before but I probably did. I'm going to check out the archive and listen to some past interviews.
