Or...you could drop a model you just finished and then step on it trying to get out of the way, or knock a model shelf down trying to put one too many models on it and watch the models air drop to the concrete floor, or, place an unopened kit box on the seat of your bench chair...and then, after forgetting that you did that and rapidly find out that you did when sitting down at the bench...just start from there for the "crushed" look.
