I usually say that it just happened that my internet related hobby turned out to be profitable for the time being. I say hobby because first, I can't call it a business - too unstable, too organic traffic related, too... you name it; second, when people hear "hobby", they usually stop investigate further. No "how much do you make?" questions.
