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. So, 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 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, too."
