Okay before I say anything else I just want to say that clowning, and funniness comes from you. It is not in props, costumes or skills. It is your interaction with them, other clowns, and the audience that is funny.

That being said a "gag" is a story. A gag uses props, that is, phsyical objects. What those objects are depends on the gag. How a prop is gimmicked depends on how you plan to use it in the gag.

Clowning in not like magic. With magic in a show you have a serise of tricks you impose a story and an order to. The central part is the tricks them selves. With Clowning it is the opposite. You tell a story, and the use the props to help do it. The central part is the story.

All that being said, if you are thinking about building some stuff, just for the fun of it that you can use whenever. Think visual pun. Take a pun, and try enbody it in a object. Build a pizza model out of dominos and put it in a dominos pizza box. Get a fake hot dog and drag it around on a leash. There are a ton of ideas for this sort of thing in the "props" section. But really just use you imagination. If you think "this is reallllly stupid" you are on the right track.
