Yeah, I just listened to it on Hannity.com (and I feel dirty about going to that site). To me, Marc came across well and Hannity instantly jumped on him, calling him a liar and mocking him for hosting a show about "the history of the tomato" (Sean's words) on the Food Network.
Marc clearly didn't want to discuss his career. He identified himself as someone in the industry. But Hannity pushed and Marc said he hosted Unwrapped (which led to the aforementioned oversimplification).
Hannity took Marc's statement about his show becoming a Rush clone hard and he came out swinging. He called Marc a liar and a liberal even though Marc never said he was a liberal (nor did he seem to espouse any politicial ideas).
Apparently Hannity was told by a producer that Marc had hosted Double Dare, so he used it to insult him. Marc said he was proud of his work on the show and that it had paid a lot of bills in the past.
Hannity somewhere along the line indicated that Marc couldn't understand radio and that's where Marc stopped him. Marc, of course, has a lot of radio experience...but that didn't stop Hannity from mocking Marc anyway.
Then they brought on another caller who said that Marc's OCD caused him to obsess over Hannity's show.
It wasn't pretty, but Marc didn't look bad in my eyes. Hannity just came across as a shouting bully (which, I suppose, is his schtick).
