Neat, Walrus!

And my father has noticed something similiar with baseball announcers on the radio: the call for "home run" always has the same intonation, as does the call for "foul", "fly ball", etc. And each call is very distinct.

He gets really annoyed at TV announcers, who just chat conversationally about the game (or about a game from last year) without bothering to call the plays -- they just assume you're watching the game, glued to the set.

So... back from thread drift. Did you ever try to score your commands, and if so, were they in pentatonic scale?
