It is gold. It was in the Sundance Film Festival last year. The simplest, but most entertaining short movie I have ever seen. Beautiful.

"After the completion of a feature film, Jay Duplass was left with some extra cash, a heap of spare film, some rented equipment and a lingering need to explore the universally frightening idea of resetting an answering machine's outgoing message. The resulting short film has garnered both critical praise and crowd appreciation on the festival circuit."

If you have a few mins to kill, watch it.
