Indeed that is so Sir. However, people come to a magic show to see magic. The story serves the magic. It takes a mere trick and gives it meaning, reality, and depth. People come to a clown show in order to laugh. Props alone cannot do this. It is the story and character that makes people laugh. The props only enhance it. Give you something to interact with.
When you are a magician you think "These are the tricks I know, now how do I present them?" when you are a clown you think "I could make this situation really really funny, what do I need to convey it?"
Prop making is a incredibly valuable skill in the clowning world. But you have to know why first.
