Yeah, they've done that before
As an ex-programmer, I hate this kind of stuff. The PD's job is to build a station that's consistent, delivering what the listeners expect
every time they punch in. Stunts like this may draw some short-term cume, but they only piss off your core listeners, who may or may not return once the stunt is over. But this sort of lame idea comes directly from the guys in the gray flannel suits, and PDs don't really have much say in the programming anymore, do they?
Sorry, my cynicism is showing
