Jim Vieira, co-host of "Search For the Lost Giants" on History Channel join Todd on this week's show. Jim, along with his brother Bill Jim are on a quest to investigate an incredible theory: that the myths and legends we’ve all been told about giants are actually rooted in fact. Jim has researched over 1,000 accounts of skeletons seven feet tall or over unearthed across America in the 19th and 20th centuries.

Todd is joined on the show by Grant Cameron, a well-known UFO researcher and the consciousness science and author of the following books:

• UFOs, Area 51, and Government Informants
• The Clinton UFO Storybook: ET Politics in the White House
• Managing Magic: The Government's UFO Disclosure Plan

Todd is joined this week by Ralph Blumenthal, author of the new book "The Believer: Alien Encounters, Hard Science and the Passion of John Mack."

"The Believer" is the weird and chilling true story of Dr. John Mack. This eminent Harvard psychiatrist and Pulitzer Prize-winning biographer risked his career to investigate the phenomenon of human encounters with aliens and to give credibility to the stupefying tales shared by people who were utterly convinced they had happened.
