: : : What is the etymology of the phrase "bats h i t crazy" or "bat s h i t crazy"?

: : : Does this have something to do with a malady afflicting guano miners?

: : : Or is histoplasmosis or nitrate poisoning involved?

: : Bats = crazy. Probably from the way they fly around in a seemingly crazy manner. I don't know how bat-sh*t crazy would have evolved.

: "Boring as bat sh*t" is a very common expression which has been around for at least 20 years in Australia, although why bs would be boring I don't know. Pamela

Doesn't "bats" as an adjective meaning crazy come from "to have bats in the belfry"? ~rb
