XP - Windows Speaks Slang

Some fun with Windows Speech and found this.

Follow these steps :
1. Go to Control Panel.
2. Open up "Speech".
3. In the preview box, type "Crotch".
4. Press "Preview Voice".

Instead of saying "crotch", the voice will say "Crow's nest".

Parameters that may be irrelevant:
I'm using Windows XP SP2 native, and the voice i'm using is Microsoft Sam.
