Some people seem to be able to come up with ideas on the spot. All they are doing is putting pieces of a puzzle together. They ask, "What if..." and then see what might happen after that.
I'm giving you a turkey. Ask yourself, "What if a turkey _____________?" Or "What if a rafter (a group of turkeys) wandered into _________________?"
Answer this question 3, 4, even 5 times. And try to get more outrageous with every answer.
For example (because I'm one of those people who easily comes up with ideas):
What if a turkey were bulletproof?
What if a turkey were as fast as a cheetah?
What if a turkey could use tools?
What if a turkey family ate a person every Thanksgiving?
