The lesson
Make the ad about the material, and let a scene with no dialogue explain where the product comes from.
In "Meet Your Shoes", a man has his head clipped at a barber's, walks out of town in Wool Runners and meets a sheep on a hillside. The visible frame shows him in a striped cape with a barber working behind him. The description reads "Since our shoes come from sheep, you probably could meet your shoes."
Don't copy the sheep gag; it only works because wool is the material. Keep the idea of dramatising the one fact about your product that a rival can't claim.
