"The Bob Next Door" is a television programme presented as a single episode.

Determined to prove his theory, Bart sets about gathering evidence and planning how to expose the impostor. The narrative centres on the clash between the neighbour’s growing popularity and Bart’s relentless quest to unmask what he believes is a hidden threat.
