(back before the days of smartphones & internet everywhere)
I once was sick in a foreign country and bought some chewable vitamin C that turned out to be those fizzing tabs you put in water - cue foaming at the mouth and utter confusion.
Happy it was still edible, just not in the way I tried to consume it.
I work in tech and often have to create accounts for testing or to hand over to clients. I was so happy when we hit 2019 and Jan 1, 2001 became a valid birthday, 01-01-01 in any date order.
