Fun, but very weird

Sitting in the car, waiting for your wife, while playing Treasure Island Dizzy on your phone, and suddenly having your ears accosted by the game music blaring out of your car stereo speakers is an odd and, if you're as unprepared for it as I was, deeply unsettling experience. Possibly pairing my phone with the car kit should have made me expect this, but it's not the sort of random, uncivilised behaviour you'd expect from a treo!
