Time to add 'master storyteller' and 'public fornicator' to the ways that you can describe Bryan Cranston.

Last night on 'Conan', Cranston recounted a cautionary tale for couples everywhere about getting down to business at the behest of others.

Cranston and his wife of 28 years celebrated their then honeymoon with a trip around Europe and, blessed with a 50-minute window of darkness in their car on a train through a tunnel in Switzerland and on the suggestion of their travel agent, decided to engage in 'the act' right there in the car.

And of course, things did not run smoothly.

You know how this story ends before it even starts but seeing Cranston tell it is a gift all of its own. Just don't do what Donny Don't does.
