One of the pillars of success for your show is that, never having actually met you, the audience feels like they know you. Play “Do You Trust Us?” with them. Wonder out loud if they trust you and ask that they call, but don’t give them this question until they’re on-the-air with you. Then, once on, ask if they trust you enough to give you one of their passwords. Hear the discomfort, then if they step up to the test!
