I have a couple of favourite ones but one I always think of immediately is a time when I was tasked with fixing some dashboard.
Sometimes students scores would be appearing as zero despite their average score being not zero.
Turns out it was some very simple averaging that didn’t filter out tests with a score of zero. That zero would then basically poison the entire calculation and only produce zero.

I don’t know how interesting that one is though.
