Guys frequent the fishwife’s town store
And leave stinking of fish and what’s more:
Crates of herring and lox,
Cod and perch by the box
And the cases of crabs no one asked for.

A slang term for pubic lice, tiny insect parasites that are often transferred from one infested sexual partner to another, is “crabs,” because under a microscope they superficially resemble their namesakes. The eggs they lay are called nits. A person who’s said to “nit-pick” or “go over something with a fine-toothed comb,” is one who is obsessive or meticulous about details, which well describes the persistence and vigilance required to remove every single louse egg from your pubes.
Bā namak! Funny!
