But I seldom, if ever, go out looking for a specific item needed for a pre-written skit. It works kind of opposite. I see interesting or odd items, and they generate skit ideas that utilize them! For example, I might find a hat with a large pair of lips on them. "That looks funny," I think. Then an idea for a skit where a character wears such a hat suggests itself. If it seems promising, I'll buy the hat, then go home and write down the skit idea that came to mind. When I have the time, I'll sit down later and think it through, developing it into a full-blown script.
Now, few of those type of ideas end up on this script site, since you may never find a prop or costume item just like that. I try to post scripts that use easy-to-find props. However, it demonstrates a technique that you can use to develop your own skit ideas. Seldom do skits come by sitting down and saying, "I shall now write a skit." They come by capturing the odd ideas that float through your head, mostly prompted by something you see or hear. An interesting prop, anecdote, sermon, song, etc., that gives you a kernal of an idea that you jot down and develop later.
That's how most of the ideas for the scripts on this site come about; by harnessing the ideas that flit through my mind all during the day, and saving them for future work. Don't depend on your memory, you'll forget it. Jot it down quickly and save it. I have a text file on my PC just for saving ideas. Regularly I'll open it up, go over the large collection of thought and ideas, and pick the one that is the most promising for what I need. Most of them do get developed over time. Others just float there, in limbo, waiting for the day when they too, might be picked for development.
So, watch for junk as you browse your local garage sales or flea market. You might be surprised at the treasures you will find that will spark an idea for a great skit! And you never need tell your audience where you came up with it. It's our secret!
