Just picked these up from the MacNN OS forum.

1. Mail-->Show Package Contents-->Contents-->Resources-->senders.tiff. Open it up in Preview and make sure the drawer is open.

2. Select “Go to Folder” from the Go menu in the Finder and enter the following path:

/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/ test/

 Now double-click on the audiotest.au file.

Just for fun to brighten your day a bit.
