Junk in the trunk
Flip though your junk mail and create a short story based on an advertisement. Hooray, looks like you got the new Costco mailer! Flip though that sucker and write a story about why the lady with the white jeans is so happy about her vitamins. Or the dog on the rug in the new Crate in Barrel catalog is named Randy. He's a rescue who simultaneously farts and barks whenever someone new comes to the door. Okay, now you try!
