When I was married to my first wife, if I came up and hugged her from behind and gently kissed her on the neck and there were no witnesses or recording devices, she would call me "Mr Wonderful." If I asked her to repeat it in front of witnesses, she'd call me "*sshole."
She died recently and instead of either of their fathers, I was honored to be the only ex-husband out of 3 that the kids
wanted to speak at her Celebration of Life, which was attended by about 50 of her closest friends. I mentioned the "Mr Wonderful" nickname and got a huge laugh out of it. A lot more laughter than was necessary, in my opinion.
Now my stepdaughter stays in touch and she keeps calling me Mr Wonderful.
We're still working on the laughter part...
