A client brought a litter of golden retriever puppies to my veterinary clinic for inoculations and worming. As the look-alike pups squirmed over and under one another in their box, I realized it would be difficult to tell the treated ones from the rest. I turned on the water faucet, wet my fingers, and moistened each dog's head when I had finished.

After the fourth puppy, I noticed my hitherto talkative client had grown silent. As I sprinkled the last pup's head, the woman leaned forward and whispered, "I didn't know they had to be baptized."
