Marty Tirrell and Larry Cotlar - broadcasters at Des Moines area station KXNO - got in a bit of trouble
recently. Those two got into an F bomb laced "discussion" during a commercial break when they thought they were off the air. Problem was they weren't off the air.
Somehow a switch got thrown so their microphones were live. Any one in the area who happened to be listening got to hear their F and other word salad in the background while commercials were playing. I found a YouTube clip with audio
of their little disagreement. It's not bleeped out, so it's NSFW.
