They really didn't need to have the mic's turned up when Wes and Ken were talking and that's why they probably didn't keep it in check thinking they were off. By the way, they can be controlled other than the receiver on the bowler.
The Brian Voss show was the 1997 Northwest Classic. It was live on ESPN and he did go "F*** Yeah!" which was unbleeped at the time when he was walking around after the game was done and then realized he still had the mic on. Marshall Holman made a joking comment like "well, we are now a rated R show"
