This finally cleared up a really stupid bit of confusion on my part. I knew that a couple of the wires on a phone were called "tip" and "ring". I knew what "ring" must do, but didn't understand why they called the other "tip", I figured it had something to do with taking it off the hook.
I never once thought of the standard 1/4 photo plug.

and to tie into Dan's current series of photos:

In electronics service we refer to them as tip-ring-sleeve plugs. That designation goes back probably to the Western Electric Code No. 109, 110, and 126 plugs in use by 1907.
