Okay, it's gotten too quiet around here. So, for everyone's edification and amusement, here is the etymology of the word "pumpernickel" (extracted from *Panati's Extraordinary Origins of Everyday Things*):
While the Egyptians are credited with having invented bread baking sometime around 2600 B.C.E., Westphalian Germans created a variation on on sour rye bread and pejoratively named it pumpernickel, from "pumpern" ("to break wind") and "Nickel" ("Old Nick the devil"). The earliest instance of "pumpernickel" in print appeared in 1756 in *A Grand Tour of Germany*, by a travel writer named Nugent. He reported that the Westphalian loaf "is of the very coarsest kind, ill baked, and as black as a coal, for they never sift their flour." The sour rye bread was considered so difficult to digest that it was said to make even Satan break wind.
