In the clip, Kutcher asked his wife if she wanted to hear his "really dumb" idea, to which she responded, "I'm sure. What's this idea?"
"I think we should have complete strangers come and stay with us at the beach. It's so nice here," the businessman explained.
"Like, in real life?" Kunis asked.
"Ok, so we're doing it? Great!" Kutcher quickly said before the Friends With Benefits star yelled, "What!?"
"It's not the craziest idea I've had…stay with us at our beach house and leave like we're old buds! #airbnbpartner. Booking opens tomorrow at 10 a.m. PST. Link in stories," Kutcher wrote in the caption of the video.
Fans were blown away by the typically private pair allowing complete strangers to invade their space. "You're crazy for this lol," one social media user noted, while a second person warned, "Do background checks first!" and another joked, "Tell me you miss normies without telling me you miss normies. 😂"
