Buffy the Vampire Slayer - Season 7 - Eps 16: Storyteller
Andrew creates a documentary called "Buffy, Slayer of the Vampyres", a record of the current situation in Sunnydale to show to future generations. He manages to capture many important moments, and to annoy almost everyone in the house. But Buffy needs to tear him away from his filmmaking because the Seal of Danzalthar is active and Andrew may hold the key to closing it before it destroys the town.
