The boys' driving skills are tested when they experience real-life Tokyo Drift and they meet one of Japan's wackiest record-breakers. The duo go head-to-head trying to crack the most walnuts with their bottoms and Brad makes a bid for redemption by attempting a stomach-churning bungee jump. Barney decides his dad needs to learn how to be more zen.

The boys land in the warmer climes of Thailand for the next leg of their trip as they appreciate the stunning scenery from 1000 feet in the air on a motor-paraglide.
