I go with short and sweet whenever I can... My favorite line is that "I wish I could take credit for it but he just came that way!"
If pressed, I'll admit that he's come from a long LONG line of geeks and then divert the subject to his various relatives with various geeky careers and hobbies -- math teachers, librarians, computer programmers, sys admins, compulsive readers, history nuts, engineers, accountants, etc. The poor kid had no hope of being born anything but a geek and then we went and surrounded him with engineers and statisticians among our friends, and it was all downhill from there....

Now the fact that he's polite I'll take
full credit for. LOL!!
