I don't know how many of you tried the writing exercise I posted last week -- it was pretty weird. Well, I did warn you! Weirdness notwithstanding, I think it helped to prove my point that you can use anything to spark a writing idea. There is no such thing as a dirth of ideas -- it's just a matter of being open to them.
Here's another idea for this week:
Turn on your television. Take the main character from the first commercial you see, and the main character from the second commerical. Write a scene where they are having a conversation.
