~ - You know you've been hacking too long when...
...you stare blankly at the screen and your fingers type "rwho" without
any help from your brain.  ...you get tired of screens full of worthless
information scrolling so you alias rwho.  ...you subconsciously start
typing "/usr/ucb/rwho" to bypass your alias.  ...you alias
/usr/ucb/rwho, but bypass that alias simply by inserting extra "/"s.
