"My boyfriend's family took me on a vacation to New Zealand for New Year's, which is the nicest, most amazing thing in the world," Cuoco shared. "They're like, daredevils. My boyfriend is a daredevil, he loves to do all [that] stuff."
"So he told me, 'We're so excited! Midweek we're going to go on a canyon swing!'" she continued. "And I'm like, 'Well that sounds like fun, I like a swing. That's fine.'"
It turns out, when Cuoco heard "swing," she thought of the traditional, simple park swing. Canyon swinging, it turns out, is something much different.
"I start Googling it and I'm like, 'Honey this looks like a bungee jump,' and he's like, 'No, no, no it's canyon swing!'" she recalled. "I'm looking and I'm seeing these death-defying videos and people posting things like, 'DONT DO IT!'"
"But here's the problem. I'm with his family! I felt like I was on The Bachelor! I had to be like, 'Are you ready to take this [step]? Can you jump off with him? This is the next step in your relationship,'" Cuoco joked. "I'm like, 'Am I gonna get the rose out of this?'"
And it turns out that the zip line was just the beginning of the white-knuckle thrill ride.
"So I get off the zip line and they're like, 'OK, you made it. Now we're gonna walk up to the swing,'" she said, explaining that the next step in the experience requires you to jump into the abyss.
"They let me and my boyfriend go together," she shared, "They hooked us together and they said, 'OK, jump when you're ready!... It's a six-second free fall and then you swing for 10 minutes. You dangle, and you hope that you're going to see your family again."
"I was screaming the whole way down," Cuoco admitted. "It was horrible, so horrible, it really was. But I got the rose."
