Underdogs or not, the twins from Gonzales are still very much in the running on CBS' "The Amazing Race."

Firefighters/paramedics Eric and Daniel Guiffreda (#TheFirefighters) were the second team to arrive last week, finishing the Prague, Czech Republic, leg of the 21-city global race ahead of five other teams.

"I think, in the beginning, people did count us out because we kept coming in always at the end," Daniel Guiffreda said at the start of the Jan. 31 episode.

"Yeah, we would have counted each other out," Eric Guiffreda said. "Don't worry about them guys. … We'd rather people count us out instead of seeing us as a threat and running around with a bull's-eye on our backs."

Last week's episode proved cerebrally challenging for the 33-year-old Louisiana duo, as the two sat in on opposing astronomical lectures on whether the Earth is round or flat. They then had to answer 10 questions about what they had heard — no note-taking allowed. After listening to the talks several times, they eventually answered all questions correctly, earning their next clue.

Later, Daniel Guiffreda entered a dimly-lit room filled with hundreds of ringing telephones. He had to find the eight phones with a voice on the other end, each one supplying one word of a quote from famous 20th-century novelist Franz Kafka, born in Prague in 1883. Once he secured all eight words, he had to unscramble them to form the quote, "The meaning of life is that it stops."

"I'll never answer another phone again in my life," Daniel Guiffreda remarked during the tedious challenge.

This week, it's on to Zimbabwe for the six remaining teams, which also include: Cody Nickson and Jessica Graf (#TeamBigBrother); Henry Zhang And Evan Lynyak (#TeamYale); Alex Rossi and Conor Daly (#TeamIndyCar); Kristi Leskinen and Jen Hudak (#TeamExtreme); and Lucas Bocanegra and Brittany Austin (#TeamOceanRescue).

In the “All’s Fair in Love and War” episode, "for the first time, racers swap teammates for an entire leg. Also, the game becomes ruthless with another double U-turn, on a special two-hour episode," according to the show's website.

Note: The show starts at 8 p.m., an hour later than usual, this week.
