I have heard countless radio personalities throw out that exclamation before saying something provocative. It's a projection of the anxiety they feel before saying something they know is a bit out of the norm of what's deemed acceptable.He knew it was wrong. He said "I may get into trouble for this." So then why did he continue? My view is he WANTED to get fired. He's received more publicity for one little bit than he did in 25 years.
I don't, however, know of any radio talent that intentionally tried to get fired just to get publicity. They'll make a controversial statement to get publicity. They'll even maybe luck out and get a good gig after getting fired for such a statement. But I don't know of anyone dumb enough to actually try and get fired just for the hopeful publicity just to maybe land a better gig. Quite a gamble even in the best of times, and we're far from those day.
