Pre-empting my nephews entry in 20 or so years time:
I was at my brothers house and his three year old son was playing quietly with his toys. We heard the chimes of the ice cream van and William froze, my brother asked him what the chimes meant and he replied 'its the child catcher'!
'That's right,' said my brother, 'best you stay here where its nice and safe.'
- Fantastic!
A childhood belief about ice cream vans
