My real name is Ted. One day, a co-worker buddy of mine just started calling me "Thaddeus" for no apparent reason, so it stuck. Then later, it somehow got expanded to "Thaddeus Beauregard" just because it sounded formal in a funny way. My buddy has since retired and I don't hear from him as often. So, I chose my user name partly because I couldn't think of anything else, partly because it made me laugh when he would call me that, and partly to honor my friend and the fun times we had bs'ing at work.
