In hindsight, I thought it was kind of crummy how he clearly ambushed them. They had one idea of what they were speaking about, and he went off the rails almost immediately. That shit was planned.
The alternative is he says straight up he wants to come on air and skewer their show and then mysteriously gets uninvited for some reason.
Sure he ambushed them, but there's no way other for him to get on that show and make that point by being upfront about it first.
edit: holy shit, this was 10 years ago?!
