'Conan' is usually funny-funny, but last night he was funny-serious, as the host officated a wedding between his costume designer Scott Cronick and his partner David Gorshein for his final show in New York City. The touching union also made late-night TV history.

There was still plenty of room for levity, as Conan made jokes about the two families not getting along.

Cronick also asked to be walked down the aisle by a certain host of a popular Bravo show. Find out who it was, and check out the moving ceremony below.
