The First Name of Mrs. Columbo
At last a great mystery has been solved. The hitherto unknown first name of Mrs. Columbo, the wife of TV's famed Detective of the same surname, is now known. Dolly.
Mrs. Columbo 
A few years after my mother's last cat, Boots, passed away she decided to get another cat. Two, actually, so she could name them after her two favorite TV characters, Perry Mason and Columbo. It took a few more years, but last Christmas she couldn't drag her feet any more so I picked out a cat at the local shelter (or Public Cat House, depending on your sense of humor) and she said "Great, we'll name him Columbo!" despite knowing the cat was a girl.
We were reminded of this during the adoption process when the shelter lady (or Madame, to extend the joke) said "That's a boy's name!" Mother quipped back, "Then it's Mrs. Columbo!" It was I who decided that since the cat already had a name we should keep it, too, so she became Mrs. Dolly Columbo. Now the world knows what the original TV series refused to reveal. Just don't tell my mom that the "sequel" program titled Mrs. Columbo gave the character the first name Kate.
