If you can't think of anything interesting to write, you can use story prompts to get your mind moving. You don't have to write a full story about these silly story prompts, but they can at least help you get your pen moving and give you inspiration to write something else phenominal:
1. Stuck in a Storm
Put a group of random people together, and they have a storm keep them locked inside for longer than they'd like. The more diverse the group, the funnier the story will be. They might all be students at a university. They might be women trapped at a book club. This is one of the story prompts that can take off in several directions, so it's all up to you.
