This week, the pair decided to call back to that mishap -- and the pyrotechnics that were missing during their last redemption performance -- with a jaw-dropping routine that began on a trapeze swing and ended with the pair pulling off roller skate acrobatics that blew the roof off the place.
After showing their deft ability at trapeze stunts, Tyce let Mary fall and then dove off after her as fire erupted from the stage.
Emerging like sexy phoenixes from the flames, the couple donned roller skates and stepped up on a raised circular platform, where they pulled off some incredible, death-defying spinning stunts that saw Mary hanging on to Tyce's neck with her ankles as he whipped her around in circles, her head coming frightening close to slamming into the stage.
All the while, the heart-stopping act was set to a slow, emotional rendition of "(I Just) Died in Your Arms," which felt like an intentionally ironic musical choice.
After the performance, the pair came together with host Tyra Banks to hear what the judges had to say, and all four of them were nearly speechless after the breathtaking routine.
"I thank you for nearly giving me a heart attack twice. How many ways are you trying to find to murder your wife?!" Simon Cowell said. "When we ask people to step up their game for the semifinals, that's what you call a step up. It was sensational!"
Cowell went on to praise the performance, calling it "the best act of the night."
As for Howie Mandel, he was stunned by the couple, but worried about the message it was going to send to their 2-year-old son.
"I know kids wanna grow up and be like their parents. He's gonna light fires in the living room and wear roller skates with no helmet and hang upside down from the curtains!" Mandel said, laughing.
