Whoops! Bryan Cranston revealed to Conan O’Brien during an appearance on Thursday, August 11, that he and his wife, Robin, got caught having sex on a train in Europe on their honeymoon.  

“My beautiful wife Robin and I, who celebrated our 28th anniversary recently --admittedly a cheap applause line -- we were in Europe for our honeymoon and one of the parts of the trip was to go from Switzerland to Italy, and they said, 'Take the train,'” Cranston recalled. “The travel agent said, ‘By the way, the third tunnel is 50 minutes long. It’s traditional for honeymooners to take advantage of that time.’”

When their train entered the tunnel, Cranston continued, they decided to follow the travel agent’s recommendation.

“We’re reclining, going, and we’re enjoying our love making,” Cranston recalled. “Within a short period of time, I start seeing the features of my beautiful wife’s face, and I’m thinking my eyes are getting acclimated to this… Within seconds, wham, we’re out in broad daylight.”

The actor said that everyone around them — including their kids — could see everything they were doing. 

“And my gorgeous wife says to me those three words you always want to hear, ‘Get off me,’” he jokingly concluded.
