A well-known character in Young Frankenstein, played by Cloris Leachman. What's funny is that each time her name is mentioned, the horses in the castle start to whinny and jump up and down. A great running gag for the movie, up until the end.

Marty Feldman / Igor walks back into the castle, turns around and yells out Blucher! and the horses all Whinny. Even in the dungeon, when her name is mentioned, you can hear the Whinny from far away.
