I used to think that ice cream vans were "kid police". The police in my neighborhood drove around in van-like cars, and since I knew that police arrested adults, and that their cars played "music" when they were chasing somebody, I thought that the music coming from the ice cream vans meant the kid police were coming to arrest me.
