I've had a pseudo-tradition with some buds for the past decade or so. Every Mardi Gras, we admit to something weird we've done the past year and to some personal oddity that may not be public knowledge.
I was too busy with remodeling to do anything particularly odd last year, so I had to make two admissions:
I adore things from the 40's - clothes, music, decor, ads, cars....this seems to astonish people as they connect me with Victorian stuff.
There's one guy old enough to be my father I would have done in a heartbeat.

He died in 1995 and was cremated, so no remarks about popping in for a cold one, thank you.
