The last time contestants faced a food-based Road Block on 'The Amazing Race' (Sun., 8PM ET on CBS), it proved to be too much for everyone that tried it and they had to switch tasks. Perhaps it was because they were in first place at the point they reached it, but Zev and Justin decided again to tackle one.

!!SPOILER ALERT!!

They arrived at the challenge with Kisha and Jen hot on their heels. They had to eat a huge pot of fondue cheese, but the big difference between this and the last food challenge was there was no time limit and because of that Zev was confident they could finish.

This is shaping up to be a rather odd season of 'The Amazing Race.' Mind you, not quite as odd as that ill-fated (and I hope they never entertain the notion again) "family edition" some years back. That was annoying odd. This season is just plain unusual odd.

It's not just that all the teams are folks who didn't win before. It's technically not even an "all stars" season as some of the teams didn't make it all that far at all or made horrendously stupid errors resulting in their previous eliminations. It's odd for some of the things they're doing this season.

To be successful on 'The Amazing Race' (Sun., 8PM ET on CBS), we always hear about the importance of hard work, focus and luck. But we never hear enough about the importance of paying attention to the details.

That crucial facet of the game seemed to be completely lost on dating Goth couple Kent and Vyxsin from the moment the most recent leg kicked off. They immediately got lost on their way to the airport, missing a crucial flight. From that point on, they were playing catch-up.

They pulled to within one team, Zev and Justin, but another mishap has them on the brink of destruction. Headed to the next point on their trek, the pair realized they were missing their fanny pack after boarding a bus on a winding, narrow road.

What's the absolute best thing about 'The Amazing Race'? Sure, there's the adrenalin rush as the teams race around the world. Yes, there's Phil's infamous eyebrow raise. You can cheer on your favorite teams and jeer at the ones who irk you.

But the best thing about the race is learning odd trivia about other countries as we peek into their cultures and traditions. Yep, now we can add the Frog of Luck into our everyday conversations. Life is good.

No matter how hard you prepare for 'The Amazing Race' (Sun., 8PM ET on CBS), you simply can't prepare for the unknown. And nowhere does the unknown seem to rear its ugly head more than when it comes to the myriad flights contestants must take.

At the beginning of this season, which features contestants who've raced before but never won, host Phil Keoghan said that second chances don't come easy. A few short hours later on their very first flight, that proved to be even more true than they might have imagined.

After an opening challenge saw eight of the eleven teams secure a position on an earlier flight to Australia -- with a 90-minute lead on the second plane -- the unexpected occurred. A man on the lead plane had a heart attack mid-flight, causing it to make an emergency landing in Honolulu.
