22. Wilmer Valderrama, Mariah the Scientist

Actor Wilmer Valderrama stops by to chat about the new season of "NCIS." R&B singer-songwriter Mariah the Scientist will perform a medley of "Is It a Crime" and "Burning Blue" from her new album "Hearts Sold Separately." Then, Jennifer meets Misty Combs, a nurse from Whitesburg, Kentucky, who went viral after helping a mother raccoon rescue her babies from a dumpster. She even performed CPR on one unresponsive baby raccoon that had ingested moonshine-infused peaches discarded by a nearby distillery. Thanks to Misty's quick thinking, that little raccoon survived and was eventually released back into the wild.
