Combat veterans, many of them from Special Ops, have found success in Las Vegas, where they’ve created a business that allows people to battle zombies in a global apocalypse. It all happens inside a massive facility east of the Strip—bringing in about $2 million a year—and it’s all strangely real. But to the men who created it, these battles are not just about money. They’re therapy.

Two bored realtors in Calgary, Alberta, kept trying to come up with a “big idea” to make money.

Ed Currie was so miserable he wanted to die. Then an angel appeared and told him to live. Now he runs a hellish enterprise, growing the hottest peppers on Earth. How hot? “Stupid hot.” It’s made him rich. It’s also made this reporter sorry she ever took him up on the offer to taste one.

A divorcee in Portland just wanted a hug, but all the men she met assumed that meant sex. It didn’t, and the only way she figured anyone would take her seriously is if she charged money to cuddle. It worked. It’s weird. It’s Portland.

Matt McMullen accidentally fell into the sex doll business, but he has never regretted it. He makes the Real Doll, the most popular, most expensive, most...realistic...sex doll on the planet. Sales in 2018 could reach $3 million with a new model that has a robotic head. The artist-turned-entrepreneur has strong views about making his dolls in America, and he also believes they have therapeutic value. We interviewed McMullen on camera in his studio in 2016, but we decided at the time that the visuals were a little too graphic. But this is audio! Hear what we wouldn’t let you see. It’s one of the strangest successes ever.
