'The Amazing Race 21' finale preview: The Fabulous Beekman Boys finally step up their game [Exclusive video]

And then there were only four.

Dating Texans Trey and Lexi, "twinnies" Natalie and Nadiya, Chippendales Jaymes and James, and Beekman Boys Josh and Brent have just one final leg between them and the million-dollar prize in "The Amazing Race."

Judging from this exclusive preview clip from the finale, it seems the habitually last-place goat farmers are stepping up their game and playing to win. As the teams scour the expansive gardens of a chateau in France's bucolic Loire Valley looking for a stone dog, they spout "dog," "woof woof," and even the Spanish word for "cat" (serious "d'oh" moment, sisters!) randomly at other visitors and employees. Just when it seems the language barrier will strike again, Josh busts out some French and gets directions from the groundskeeper. The ankle recently twisted also appears to be feeling much better as he makes a mad dash toward the concrete canine.

Feeling emboldened, Brent starts a round of friendly smack talk. "Are you guys starting to sweat a little bit? The gays are going to beat you."

Their last-leg surge does not go unnoticed by the Chippendales. Jaymes jokes, "Oh, wow. Wait a minute. These boys are pulling all kinds of tricks. Josh just starts spitting French at somebody and apparently he's got a bionic ankle now. This race is on."

Tune in to CBS on Sunday at 8 PM to see which pair is the first to find Phil and the final mat in New York City on the two-hour finale of "The Amazing Race."
