Most people have told a little white lie or two, but Dr. Phil’s guest made national headlines when he was accused of duping the entire country. Tim Poe recently showcased his singing on the reality TV show America's Got Talent, and claimed that he was wounded by a grenade while on active military duty in Afghanistan and suffered a traumatic brain injury, resulting in a stutter. Shortly after the show taping, reports surfaced that he might be a phony. Tim says any lies were unintentional, and that he often gets confused because of his brain injury, and he wants to clear his name. But, is that also a lie? How will Tim respond when he is confronted by people who say they are certain he isn’t being honest? His ex-girlfriend, Alteen, says she saw Tim pretend to stutter at a karaoke bar years before he went to the Middle East, and a member of Tim’s National Guard Unit, Specialist Justin Doerfler, says there was no grenade explosion. When Dr. Phil drills down, will the truth finally come out? Tune in and decide for yourself: Is Tim the victim of lost memory, or is he victimizing others with his lies?
