Marshall and Lily met in college. It was love at first sight. They dated and even got engaged but Lily called it off, moving to San Francisco to focus on her artistic interests. They were separated for three months due to this, finally getting back together a few months after Lily's return to New York, and getting re-engaged then married. Eventually, they found out that Lily was pregnant, and she gave birth to a boy named Marvin Wait-for-it Eriksen.
