On Conan, Bryan Cranston described in detail the story of how when he and his wife Robin Dearden were on their honeymoon traveling on a train in Italy they were pretty much encouraged to make amoré in a pitch black tunnel. Cranston said, "The travel agent said, 'By the way, the third tunnel is 50 minutes long. It's tradition for honeymooners to take advantage of that time.' I said, 'Kapeesh.'"
Cranston and Dearden were sitting in a car which was parked on a flatbed on the train along with other people in cars. With the challenge laid down by the travel agent, Cranston turned to his wife and said, "Are you ready to use up seven calories?"
With the romance turned up to 11, the two got busy, but they quickly realized that travel agent might have exaggerated about those 50 minutes of darkness. Cranston said, "Within seconds -- wham. We're out in broad daylight." "What happened to the 50 minutes?" Conan asked. "Yes! That's what I said!" said Cranston.
But they weren't the only people on this train and with Cranston and his wife caught in the act, the scene got rowdy. Between the hooting Italian men and the disappointed Italian grandmother, Dearden was understandably embarrassed. Cranston said, "And my gorgeous wife says to me, those three words you always want to hear. 'Get off me!'"
