I use a command line random password generator and just paste in random text for each answer. Then I add them to the notes field on my password manager.
Recently I was asked one of the questions to verify me to my bank, and I answered, “let me spell my first pet’s name ‘papa uniform eight…’” The person on the other end of the phone was not upset one bit. Either I got it right so she didn’t care, or she’s encounters enough nonsense answers, that as long as it’s right, it doesn’t matter. No, “you really grew up on a street named ‘Quuic3ri’?” type comment.
