Sunday’s episode of The Amazing Race had its contestants running and sweating around Vietnam’s crowded Ho Chi Minh City.

Some teams are getting used to the frenetic pace and working well together while others are already starting to come apart at the seams. Too bad they didn’t have our rules with them. –Carrie Bell 1. Get your bearings: For the first time, the pit stop was not stationary. Overnight, the boat sailed to an undisclosed city and the clue didn’t tell teams that the water puppet theater they were looking for was two hours away by car. The Massachusetts Almost-Marrieds (Lance and Keri) fell behind when they assumed the theater must be around the corner and wandered the streets. The teams that asked locals for help immediately got a head start. 2. Puppets are immune to feminine charms: Grabbing the clue from wily dragons’ mouths proved more difficult than most imagined and players with good timing, longer reach and no fear of getting wet retrieved them the fastest. Hot Chips unsuccessfully tried a come-hither finger while the celibate country singers (Mika and Canaan) used dance moves. But a swift snatch wasn’t all they needed. The Almost-Marrieds failed to realize they had to unscrew the bullet to find the picture stamp that instructed them to find the post office.
