Three men were standing outside a dog obedience school with their dogs.
The first man’s dog was pulling on the leash and parking at almost anything. He said, “My dog’s such a good guard dog, she’ll bark at strangers over a block away to warn them to stay away.”
The second man’s dog was stumbling around, bumping into things, but not to be outdone, he said, “My dog’s such a good guard dog, she’ll knock over anything or anyone to protect me and my family.”
The third man’s dog was old and tired. She was curled up in a circle, snoring loudly. He said, “My dog’s such a good guard dog, she guards me against having too high an expectation of what she can do.”
