The article mentioned talking about what celebrities each of you would enjoy. There was an episode of 'Friends', where Joey and Rachel each picked three people that they could have permission to be with if the opportunity afforded itself.
The funny thing is that Joey actually had an opportunity with an actress he'd wanted for a long time but he hadn't chosen her to be one of the three. He suggested that they, he and Rachel, could make changes and he dropped one of his and added the one he had the opportunity with. When this one found out she wasn't one of his first choices, she dumped him.
I just tried to find that episode and couldn't. I remember after my wife and I watched it, we both made our lists. It was fun.
But for someone wanting to bring the subject up with a spouse, watching that episode would be a great way to open the conversation.
