"The government ... wants to repeal the [Margarine Act] because they believe people can distinguish the difference by now [between oleo and butter]."
Except for Unitarians. In the nuclear family into which I was born we have a joke. Mom likes to have I Can't Believe It's Not Butter on the dinner table along with butter. When we gather for a reunion dinner my sister's role is to say "please pass the Unitarian butter."
After their cradle Episcopalians were all grown and out of the house Mom and Dad converted to Unitanianism. More recently they've become a two-faiths couple. Dad's still with the UUs. Mom's joined the Quakers.
