A retired accountant from Queens, N.Y., has attended over 660 tapings of Saturday Night Live going back to the very first episode.

Louis Klein, 64, spent 15 years nearly every weekend on the overnight line for tickets at the show. Then SNL producer Lorne Michaels gave him the first permanent ticket to the show, according to the New York Daily News, allowing him entrée anytime. Klein later married another SNL fan from Denver, and she too was given a permanent ticket to the show.

But Klein still likes getting online and mixing with the fans waiting to get inside, while offering them advice on getting into the show, and memories of the cast members past and present he has met. He can probably give them some good financial advice too.
