Jaeger's Law

Based on my experience at the strike yesterday, and the show in general, I have created a law that applies to the use of tie line (the cord that is used for hanging cable in theaters). It is called “Harpo Jaeger’s Law of Tie Line Use” (or “Jaeger’s Law” for short), and reads:

You always need more tie line than you think, even if you take into account Jaeger’s law.
