I'm prompted to ask this question in response to the very first comment on this post:
The comment supplies a link to this YouTube video, in which russianracehorse tells "The Butterfly Joke". A Frenchman, an Italian, a Spaniard, and a German each pronounce the word for "butterfly" in their own language. The words for "butterfly" in the first three languages all sound soft, delicate, and mellifluous. Finally the German chimes in and shouts vehemently, "Und vat's wrong with [the joke teller could have said 'mit'] Schmetterling?"
