A group of friends are sat around a table playing a D&D like tabletop game.
The Fantasy
Close up of the table, characters and quest. Over top the Dungeon Master narrates the story to the players. He/she is ready from their notes to describe the setting and gameplay.
The Reality
Pull in close to show the D.M getting really excited about the story. Big body language and descriptions.
The Call to Action.
The perspective changes to the heroes fighting monsters and performing the narrations from the D.M. The battle is about to culminate with the heroes defeating the monsters in a final crescendo when..
Record scratch! The D.M can't think of the right word! He scrambles frantically over his notes but can't think of the right word or phrase to describe the scene. The mood drops! Everyone's faces contort into confused smiles or disappointed scowls!
Cut back to the game where the monsters, with the clearly superior vocabulary, have completely demolished the heroes. A voice over would say something along the lines of "Don't let difficulties with writing limit your adventures! Take a class at The Muse Writing Center today and fulfill your destiny!" with the tagline: "The Muse Writing Center: Write For Initiative!"
