"The S.P.C.A. reported at noon today that their phone had been ringing steadily all morning, keeping one person busy just answering it, and all the callers were individuals who were victims of April Fool.
The majority of the calls this morning were from men, it was reported, who asked for 'Mrs. Kat' or 'Is Miss Kitty there?'
It seems that someone leaves word that an intended victim is to call the number and ask for either of the above characters." [The Hagerstown Daily Mail
