How to Retire an Andy | eHow.com:

• Start out each day by dialing for a businesslike and professional attitude on your Penfield.
• Always review your poop sheets.
• Keep informed about the newest model of android, and what they're capable of.
• Never laser a human by mistake.
• Never become emotionally or romantically involved with an andy. It's illegal and you may develop empathic feelings for it.
