The ad in the local newspaper read: “Purebred Police Dog $25.”
Thinking that to be a great bargain, Mrs. Jones ordered the dog to be delivered.
The next day a van pulled up and left her the mangiest-looking mongrel she had ever seen.
In a rage, she telephoned the man who had placed the ad. “What do you mean by calling that mangy-mutt a purebred police dog?”
“Don’t be deceived by his looks, Ma’am,” he replied. “He works undercover.”
