Bang bang

Rule Britannia,
Marmalade and jam
Fire Chinese crackers-up-yer-arsehole
Bang-bang-bang-bang-bang.

As I believe the ditty goes.

I seem to have spent the past three nights noticing flash-bang from behind the curtains, rushing to the window, opening the curtains, waiting to see another firework go, getting bored, walking off, only for flash-bang again behind me...grrr.
