To extend for a minute what WYTZZ95FM said in regard to callers sounding well on the air.

Time and again, men and women who are working enter into radio station contests. That's fine.

It's when they win, the problem arises. What the listener often hears is whispering. The DJ asks why and said winner tells the radio audience they are at work and will get in trouble with the boss if found out. It effectively destroys the excitement and kills the momentum.

To use WYTZZ95FM's example; imagine a segue from a winner who whispers to a Metallica song.

Special thanks to everyone who participated in this thread which I originated. It's appreciated.
