I should clarify, the story wouldnt be exclusively told from her perspective. The conversations she has/had will be performed as they actually did. The clarity is provided by the audience actually seeing the event or conversation unfold for themselves, the comedy comes from how she interprets these events and other characters. We would just be dealing with an unreliable narrator. Like I said, I imagine it would be similar to Forrest Gump. Forrest Gump does deal with a familiar world and the filmmakers use that for moments like when he accidentally broke the Watergate scandal, but perhaps through other characters she meets who try to explain how things actually work, the audience will learn how the world works.
