I need some ideas for this short story assignment. Anybody up for some creativeness?

First of all, I’m not asking you to do it for me!! I just need some help coming up with some ideas for a good story.
Second of all, this is a weird assignment. The story (which has to be 600–800 words) has to include these three things:
-a red, collapsible 1-cup measuring cup
-a brown recorder (the musical instrument)
-a soft-sided glasses case with a floral pattern
So, any ideas? HELP!!!!
