Sir joe, i called last night to know how you are doing, but seems you were busy or sleeping or thinking about the humour in this post. Thanks for revealing the motivation behind your username.
Mine is simple. While i was a science teacher, my students gave me the nickname 'unclefocus' that was 10 years ago. I asked for it anyway. Whenever am taking a class, i repeat the word focus so often. I urge them to focus on my explanation of the lessons than copying the notes on the board. Before you knew it, i became "Unclefocus" Some will even shorten it to "unclefofo". Fellow Teachers joined in the name calling, the school proprietor joined, and i could not help it.
I realize that its even more improtant to maintain focus on one's goals now than ever. So i added "now" to "focus" and "focusnow" became my enduring username on all membership sites.
