PLANTED CALLERS?

Last week I was monitoring Mark Levin's show and he took a call from a reporter for the Washington Examiner (I think, maybe the W. Times) and acted like it was just another caller.  It seems unlikely that this wasn't planned but I can't be sure.  

A couple of days ago I was monitoring Beck and he took a call from a woman who complained about the Fabian's being close to genocidal monsters based on a conversation her mother had with a friend from Britain who was a Fabian.  The woman said she overheard this conversation when she was only 12 years old.  This also seems unlikely to me but I can't tell if the caller was simply lying or if Beck staged the call.
