The role of photography in taming the West

We're in a saloon in the Wild West. An itinerant photographer will take your photograph for ten cents. A handsome gent at the bar is watching. The cautious sheriff, with his hand on his revolver is ready for anything, while a voluptuous bar gal sits on his lap. A moment before the shutter is snapped. Wait! What will happen when the beer lands on the pig's head?
