Pass the Biscuits Mirandy! is a 1943 short.
Down in an Appalachian "holler" with flora and fauna moving to the syncopated beat, the country folk have it made in a stereotypical hillbilly heaven. The lazy barnyard animals', lazier hound dogs', and laziest mountaineers' greatest problem in life are Mirandy's concrete like, tooth threatening biscuits. At first perceived as a problem to be dealt with on the sly so as to not incur Mirandy's wrath, it soon becomes evident that Mirandy's biscuits make her the hero of the hour, since it is turns out Mirandy's biscuits are so hard they are used as makeshift ammunition when Japanese bombers are sighted overhead, flown by the stereotypically, overly toothsome Japanese pilots
