Count me in on the soon-to-be-established "random bowl of bacon" for big family spreads (what a truly wonderful thing...)
For the slightly bizarre of my own family's holiday foods: for most of my life, certainly going back to the first holiday meals I can remember, my mother would *always* include a plate of prunes, stuffed with a bit of cream cheese and topped with a pecan. This particular item was never present at any meal except TG and Christmas.
Other than a few tastes out of curiosity as children, my brothers and I never partook of this item. Perhaps not very oddly, I don't recall any other family members or guests partaking, either, beyond a polite "give it a try.". We joked amongst ourselves, and with my good-natured mother about this tradition for decades, and a few years ago, she stopped making what I had come to think of as an odd adornment to the traditional sideboard spread.
I miss seeing those unappealing, though apparently not entirely unloved little atrocities.
