Dennis the Tomcat

Mr. Smith, neighbor to the Martins, found that their tomcat named Dennis was running all around the neighborhood, on footpaths, in dark alleys, on the rooftops. Mr. Smith called Mr. Martin and asked, "Is everything all right with your cat? He has been running around like crazy."

Mr. Martin replied, "Nothing to worry. Dennis has been neutered today, he must be running around cancelling appointments."
