pumpernickel

Just walk into the deli and say: "I'll have a lettuce, tomato and onion on goblin-fart, please."

You know, I used to like pumpernickel bread....

I love this! I'm going to eat only pumpernickel bread from now on, just so I can say "fart goblin."

Here's the etymology I've always enjoyed for the word:

German, probably from a dialectal term of abuse: obsolete Pumper, breaking wind (from dialectal pumpern, to break wind, from Middle High German, to knock) + German Nickel, goblin.

So... Pumpernickel could be translated as "fart goblin."

They had this really catchy song about pumpernickel bread on Blues Clues.

My younger sisters were watching it, not me. :P

It's not. It was made up at a bar by a radio guy who later reported it as the true etymology. After being confronted and asked for proof, he confessed.

I've once heard a story about the origin of this name. Apparently Napoleons horse was called Nickel. When the French soldiers marched into Germany during the Napoleonic wars and came into contact with German rye bread, some said that this bread wouldn't even be 'bon pour Nickel', not even good enough for Nickel.
I have no idea whether this story is true, though...
