Back in 1994 I decided to get a cellphone (bear with me – this is relevant). The Motorola flip phones were new, and much smaller than the bricks of previous years. I called AT&T, and they asked me what area code did I want? 650 was still relatively new, and 415 seemed to have more cachet, so I went with that. Then they told me my exchange would be 699, but I did have the opportunity to pick the last 4 digits. I had the idea that I wanted them to spell a 4 letter word, because my college number had ended in DUKE. We spent at least 15 minutes on different combinations, starting with me thinking of words and converting them to numbers, and her looking to see if they were available. Soon we switched to her telling me available combos, with me rapidly writing down possible letter subsitutions and seeing if I could form a word. Finally we hit FISH and I said okay.
After the phone came, I figured out that 699 could be spelled OXY, so I started telling people my phone number was OXYFISH. For a while it was my password, too, but soon I figured out what a dumb idea that was. Now, more than ten years later, quite a number of people associate me with oxyfish, so I decided to embrace it. Besides, the domain was available.
