Reformator: You’d have to check the city’s special event and temporary use ordinances first. Even a pop‑up carnival needs a permit if it’s on public right‑of‑way, blocks traffic, or draws a crowd. The police will usually respond to a permit violation with a warning, not a riot squad, unless there’s an immediate safety risk. If you want to test flexibility, the best route is to apply for a short‑term special use permit, outline safety plans, and get the relevant departments on board. That way you can prove the rules can be flexible without breaking them.

Reformator: Paperwork is a small price for clear compliance; slipping a rubber chicken into a permit form might look funny, but it could be seen as an attempt to circumvent the process. Stick to the required details, and if you want a playful touch, include a harmless decorative item in the event plan—just be sure it’s documented and approved. That keeps the police laughing and the authorities satisfied.
