Way back in college, some 10 years ago, I sat in a computer class for the first time.  On the first day, the teacher who would be my teacher for several classes and was the head of the computer department, for some reason thought my name was Dave and looked right at me, called me Dave and asked me a question.  From that point on, I was Dave in all of his classes.  So every assignment that I did in all of my computer classes from then on were done by DarrenDave and ever since then,  it's always been my computer trademark.
