In 1984, Nealon scored a breakthrough when he was scouted for an appearance on"The Tonight Show" with Johnny Carson. His performance was such a success that he was invited over to the couch to talk with the host. In 1986, Nealon was hired as a featured player for a new era of "SNL" that was considered by many to be among the best in the show's history. The following season, Nealon was promoted to official cast member. As a writer on the show, he was nominated for an Emmy in 1987.
