Thor is known for his hammer. He wields it well and it obeys his every whim. He owns it. It is intrinsic almost to his persona and identity. Comedic timing, and the successful application of it, similarly marks the skilled humorist. But just like nobody is able to tell Thor exactly how to use his hammer, no one is able to tell a would-be humorist exactly what to do with timing either. I can describe the shape of it, yes, but what you do with it....well, that is what will make you funny - or not!
