Hey, I heard a great joke. A guy walks into a dentist's office and says, "I think I'm a moth." And the dentist says, "Well, if you think you're a moth, why are you at a dentist's office?" (Oh, no, I forgot the punchline.... You can't bail out now! Stall! Stall!) ...So the moth says..."That's a good question. What kind of dentist are you?" And the dentist says, "Well, I'm a general dentist, but I...I do dabble in orthodontry -- braces and such." And...and the moth says, "Orthodontry? I hear there's great money in that." (The light was on!) But! To answer your original question, which was, if I think I'm a moth, why am I in a dentist's office? The answer is, Because the light was on!"
