Because when Cam brings up the topic it's about something like Verizon coverage from four years ago, and the rest of us assume that the man has either gotten a new phone, dropped it overboard, or succumbed to swine flu.
Boat naming, on the other hand, is a topic of perpetual interest to many.
Personally, I like Cam when he's funny. I just read a post about the naming of people who hang out in boatyards and Cam was definitely not funny! Don't get him going on sextants, either. No worries, mate. Others have done the same, and the thread went on for days.
