Starcraft Easter Egg - Valkyrie Movie Reference

Only some of you will understand this one. If you click on a Valkyrie in Starcraft about 10 times you will notice that she says the word "Blucher" (spelling may be off) and if you click again next you hear a horse neighing. This is a direct reference to the old movie "Young Frankenstein" In the movie every time someone says the name of the old lady (Blucher) a horse neighs then dies. If you've seen the movie you will know what I mean. It is a reucurring joke throughout the movie.
