The Amazing Race 4: He's a Few Ticks Away From Having a Heart Attack!

With only three teams remaining, competition grew fierce as the million-dollar prize grew closer. After taking the lead from engaged couple Kelly & Jon at a crocodile feeding route marker, best friends David & Jeff never looked back, cruising to their fourth first-place finish. Married couple Reichen & Chip, finishing second, showed some strain in their relationship when Chip accidentally ran over Reichen's foot with their vehicle. Kelly & Jon, starting the leg off well, endured a day of careless mistakes that took them from first to worst, but were saved by the last non-elimination leg.
