One can only wonder what a guy with dreadlocks might do with $1-million.

Consider the benefits of a fine shampoo – or any shampoo – perhaps?

It’s hard to say. But something’s telling me The Amazing Race 12’s hippie winners TK Erwin, 22, and Rachel Rosales, 23, will use their newly acquired wealth for good, not evil.

Whatever they do with the cash, it was mighty fun watching them get it. Sunday’s Amazing Race 12 finale was one of the most exciting hours of reality TV I’ve watched, well, ever. The adrenaline rush and the neck-in-neck competition between the three teams – TK and Rachel, father-daughter duo Ronald and Christina Hsu and grandpa-grandson pair Donald Jerousek and Nicholas Fulks – was just what the doctor ordered for a cold winter’s night. And the lack of long commercial breaks didn’t hurt, either.

It was anybody’s game from the start. All three teams departed Taiwan on the same flight to Anchorage, Alaska, the mountainous spot for the Race’s 11th leg.

There they had to grab a clue and a pack of supplies from a local shop and hop a cab to a place called Ship’s Creek. Third place team Don and Nick forgot their pack and headed up to Ship’s Creek (without a paddle, so to speak). Thankfully they remembered to go back and grab the pack sooner than later.

The final leg’s detour options were “Cut the cod” and “Grab the crab” (who comes up with these names anyway?). The former required a fillet knife and the latter involved getting pinched. Need I explain more?

Christina and Ron cut their cod and took a significant lead at this point. But climbing a glacier at a 90-degree-angle above freezing cold water proved to be a difficult task for Christina (Wuss, I do that ALL the time!).

I was seriously concerned for grandpa’s health on this one, but as usual, 68-year-old Don chipped away at the ice and pulled through – wearing shorts, to boot.

Up next was a speedy helicopter ride en route to an impossible final roadblock that saw the team members with the best memories (Rachel, Christina and Nick) placing an item from each city they visited onto a stage for the next clue.

How nostalgic! You know, I was just dying to see how that dirty bowl of camel’s milk was doing. Ditto for the donkey from Ireland and that Croatian pistol that scared the bejesus out of me in leg six.

After a few dramatic one-shots and a swift commercial break, it was revealed Rachel had the best memory (no way, dude!) and she and TK were off to the finish line.

They appeared to be neck-in-neck with Ron and Christine, but managed to pull up first for that final, glorious sprint. Actually, it was more like a waddle, as these two hippies are clearly not ones to rush such a groovy moment.

Yep, turns out slow and steady can win The Amazing Race.

TK and Rachel graciously accepted their prize, but emphasized that their deepened relationship was more important than the huge wad of cash. Of course, that will change when they realize how many incense sticks $1-million can buy.

The others had similarly touching final moments. Nick, 23, and Don both learned a lot from each other while travelling an amazing 30,000 miles around the globe.

Formerly cold-hearted sales exec Ron, 58, survived a hernia and a major fashion tragedy (in the form of wrongly interpreted “Who’s Your Daddy” T-shirts). And together, he and Christina, 26, developed something no amount of money can buy: A close and loving father-daughter relationship. Aww.
