What should have been a romantic getaway derailed the minute Kunis got her husband an RV for his birthday. "I made a boo boo," she admitted, as Kutcher decided they'd have a road trip in his new gift after their wedding. Making matters even crazier: "We also went honeymooning with my in-laws."
While the "Spy Who Dumped Me" star only splurged for a "little tin can on wheels" for her husband and their then 10-month-old daughter Wyatt Isabelle, Kutcher's family went all out for the "Taj Mahal of RV."
The trip started to fall apart as soon as they got to Bakersfield -- a town a few hours outside of Los Angeles -- where the air conditioning broke down in 110 degree weather. Then it only got worse from there.
"We almost died on the side of the road when Apple Maps took us on a road ... it wasn't a road," she continued. "It was a fire road on the side of a mountain. We all had to jump out of the vehicle and walk for like three miles while my father-in-law drove the van and Ashton, like, navigated him over gigantic boulders because there had just been a massive flood."
Reminder, this was only "like Day 2" of the trip.
The breaking point came when Kutcher's mom used outdated travel books to find them RV parks near Napa Valley. Unfortunately, they ended up in an area "an hour outside Napa, with two prisons. That is where our TV trip ended. My husband looks at me and goes, 'I quit,' and I was like, 'Me too.'"
Later in the show, she joined Fallon, Zachary Quinto and The Roots' Tarik Trotter for a game called "Say That to My Face." One by one, they each held a mask of celebrity's face over their own, as the remaining players did impressions to help them guess the identities.
Let's just say it's probably been a while since Kunis has seen a "Star Wars" movie, because this might be the worst Chewie impersonation ever.
