I recently came across 'Strange Food From Around The World'. It lists all sorts of weird and wonderful dishes, including these examples.
BABY MICE WINE
Baby mice wine is a traditional Chinese and Korean "health tonic," which apparently tastes like raw gasoline.
Little mice, eyes still closed, are plucked from the embrace of their loving mothers and stuffed (while still alive) into a bottle of rice wine.
They are left to ferment while their parents wring their tiny mouse paws in despair, tears drooping sadly from the tips of their whiskers.
Cock's combs (the wattle-y stuff on a male chicken's head, not the plant): reputedly a classic Tuscan dish.
DROPPED FOWL (U.S. Kentucky)
Hang up a fowl by the neck to age until it's ripe enough that the weight of the carcass makes it fall off the head.
Fresh raw fish (usually squid) served in a sauce made of fermented fish/squid guts. Truly awful. I'd sooner eat a quart of natto than down more than 1/2 cup of this stuff.
There's more at the link. Interesting reading . . . although hardly appetizing as far as I'm concerned!
