Friday Funny

A woman saw an ad in the local newspaper which read:
"Purebred Police Dog $25."

She thought that was a heckuva deal, so she called and ordered
the dog to be delivered.

The next day a van arrived at her home and delivered the
mangiest-looking mongrel she had ever seen.

In a rage, she telephoned the man who had placed the ad,
"How dare you call that mangy-mutt a purebred police dog?"

"Don't let his looks deceive you, ma'am," the man replied,
"He works undercover."
