Losing my image

Had a lovely couple over for dinner tonight, but I'm afraid I'm losing my reputation. All night we agreed on everything, being equally indignant over things that aren't right, over youngsters who do not know how to behave, and how some people are just plain stupid. In the end I tried to bring up religion and politics, which are two topics that for sure get people going. Usually. This time it turned out that both of them were atheists like myself, and none of them took the bait on politics. Actually, I think if I would have pushed it, it would've turned out that we share the same beliefs there too. This is a couple who have been together for 35 years and according to them never fought. Not sure I believe that, but after tonight maybe I am. Now I gotta come up with a topic for the next encounter that will get them going. Ideas anyone?
