"Dennis looked at the puppy in the window. We both did. It was the oddest thing. Normally, puppies in pet store windows sleep or pee or roll around on top of other dogs. This one ignored us its window-mates and was instead sitting with its nose pressed against the glass, looking at us with an extremely serious little expression on its face. An expression that seemed to me to be saying, "I am a sacred cow. Get out your wallet."
