I'm paraphrasing but I heard something to the effect of "drunk and passed out in a snowbank" and I think I went into a mini-Jonesy blackout rage before the host, PU, cut the guy off and got him off the air...
At the very least, bad taste and inappropriate...at the worst, who knows? Slander?
That being said, it's frickin' AM radio and who really cares what they say? I mean really, it's about two steps above the guy that has to go out and milk the prize BULL every morning...
