Jay challenges fellow comedian Alonzo Bodden to a semi-friendly dirt bike race, gets pointers from IndyCar champion Scott Dixon, and hears the inspiring story of a champion racer who became the first quadriplegic with a driver's license.

Car lovers who never want to grow up; Michael Strahan and Josh Duhamel surprise a special kid; a four-story, motorized fire-breathing dinosaur; Jay tours the 85-acre playground of Pixar's John Lasseter; and grumpy comedian Jeremy Hotz.
