"Hungy or not"
The phrase first began in Canada, where the action of eating a
prairie dog was looked at as a desperate act, that one would only commit if they were insanely hungry, whereas being willing to go out and search out a
harbor porpoise (although at the time, the split between a harbor porpoise and a normal porpoise wasn’t super well known, plus harbor porpoise or
prairie dog sounds stupid) took a long time, so you wouldn’t want to be hungry.
