word-for-today:

You might have thought card sharks and loan sharks were named after the predatory fish, but apparently there’s a decent chance it’s the other way around from an old Dutch word meaning “person that takes unfair advantage of other people”. Before that they were known in English as a haye or dogfish, which means sometime in the ~1400s enough English sailors started saying “don’t get in the water, it’s infested with those jerks”
