Pick a demographic, any demographic...

I've got the TV sitting chatting gradually to itself in the background as I'm catching up on some work this afternoon, and they're showing the car racing (V8 supercars, for what it's worth) - with some surprising ad selections in between: the last one they just showed was an SMS baby name generator service, where for a cost of only $3 per message, you can sms "your name and your boyfriend's name" to them and they'll sms back the ideal name for your baby. Pretty clearly targeted at the 'idiotic 14-year-old female with daddy paying the mobile phone bills' demographic... who I wouldn't have guessed would be spending very much of their Saturday afternoons watching car racing on TV?
