Each guest would be asked to provide the first names of some married TV couples, (i.e. The Simpsons, I Love Lucy, Bewitched, Married With Children, Brady Bunch, Honeymooners, etc.).
It would really bring back memories and make everyone think about some old TV shows.
You could also name some tv husbands and wives and asks guests to name the show.
