Act as a sketch comedy head writer. Write a {{sketch_length}} comedy sketch for {{cast_size}} performers, based on this premise: {{sketch_premise}}. The audience is {{audience}}. Before the script, name the game of the scene in one sentence: the unusual thing and why it is funny. Then write the script in standard format, with a quick setup, the unusual thing revealed early, at least three beats that heighten it in surprising but logical steps, and a button ending that lands in one line. Root the jokes in character and situation. Punch up at power, never at identity, disability, or appearance. After the script, give two alternative endings and point out one section to cut if it runs long.
