'The Amazing Race': Vanessa And Ralph Fight All The Way Up To A Fairytale Castle (VIDEO)

Sunday night's installment of "The Amazing Race" (Sun., 8 p.m. ET on CBS) found the teams heading for the glorious Neuschwanstein Castle in Bavaria, Germany.

However, the steep hike up the mountain to the fairytale castle -- the inspiration for Disney's "Sleeping Beauty" castle -- caused a dust-up between Ralph Kelley and Vanessa Macias.

The dating divorcees were at the foot of the mountain when Vanessa decided that it was too far to walk. "We can't hike that," she said, before suggesting they catch a ride on a horse and buggy that was heading up the mountain.

Eventually making their way to the castle on foot, the pair griped at each other almost non-stop. Vanessa was especially mad that Ralph had the temerity to suggest she carry her own jacket. (To be fair, he was already carrying their gnome.)

Afraid they were losing ground to the other teams, Ralph begged her to walk faster, but she refused until he agreed to carry her jacket. "Anthing else you need me to carry, princess?" he quipped sarcastically.

"The Amazing Race" Season 20 continues on Sundays at 8 p.m. ET on CBS.
