“On Thursday, at 3 PM, March 19, 2009, at the Teton County Courthouse in Choteau, Montana, I was married to Regina Lasko,” he told the audience.

The couple began dating in 1986 and, as Letterman explained, he clearly wasn’t in a rush to the altar.

“Regina and I began dating in February of 1986, and I said, ‘Well, things are going pretty good, let’s just see what happens in about ten years,” he added. “I had avoided getting married pretty good for, like, 23 years, and I – honestly, whether this happened or not – I secretly felt that men who were married admired me…like I was the last of the real gunslingers, you know what I’m saying?”

Letterman, 61, and Lasko, 48, have a son, Harry, who was born in November 2003.

However, as the bride and groom made their way to the courthouse in Montana, things didn’t go quite as planned.

“It’s me, Regina and Harry in the pickup truck… we get two miles from the [court]house and we get stuck in the mud – I mean, turn the truck over, stuck in the mud. So now we think, ‘Well, somebody will come’ – no, nobody comes along,” Letterman recounted. “So I get out of the truck and I walk two miles back to the house into a 50 mile an hour wind… And the whole way, I’m thinking, ‘See, smart ass, see, see, you try to get married, this is what happens.’”

But luckily for the late night host, he made it back in time.

“So then we get in the car and Harry says, ‘Are we still going into town?’ and I said, ‘Yes, we are,’ and he gets very upset because mom had told him if I wasn’t back in an hour, the deal was off.”
