This week's incredible kids include a pair of tight-lipped siblings, a remarkable pianist from Okinawa, Japan, and a trio of girls who give Tiffany tips about what to look for in a boyfriend. Additionally, budding comedian Evan from episode three returns to share some breaking news with Entertainment Tonight's Kevin Frazier.

Kids come in all shapes, sizes and ages. This week, we meet some kids with slick dance moves, a germaphobe, a child whose age fluctuates according to the price of a kid's meal and a 10-year-old college student. Later, Tiffany meets a senior citizen who says the darndest things.
