The Amazing Race Season 10 Episode 5 I Covered His Mouth, Oh My Gosh!

Tension escalates as one racer's slower pace causes their team to miss a bus. One racer tries to align with another team, offering to lead them to a travel agency where they may obtain help racing to the next destination. The racer simply asks that team to remember the favor down the line. Trying to be practical jokers, one team pretends to make flight reservations on a fake cell phone while another racer gets nervous and borrows a local's cell phone to make actual reservations, causing the jokers' plan to backfire.
