I used to own a lawn/landscape maintenance business and my last name begins with "Mo", which (obviously) sounds like "mow". My phone number for the business used to be MO LAWNS so it would be easy for my clients to remember.
The name doesn't really fit anymore, though. I sold the business and had the phone number disconnected.
On most of the other forums I frequent, I go by TheFishinMagician. It's because I can make fish magically appear on the end of my line!
