Reader, I did "Cat Facts" to Mr noZ for April Fool's a couple years ago. I began in early March & sent the messages increasingly more often. I got a phone number from PA & he had no clue. He was ok with once a day & interesting facts but when messages were repeated & very frequent... not so much. Got him good!
April 1st, after frantically sending messages from PA, I sent a text from my own cell asking if he had ever seen Superman & Clark Kent at the same time. Then I sent one asking if had ever gotten a Cat Fact while in the room with me.
The idea came from WS, but I do not remember which thread.
