We once had a washing machine drum break off its ballast, it was brilliant, thing went charging around the kitchen like it was possessed, destroying all in its path. Well, I say brilliant, my mum wasn't too pleased
I think it's so funny because of the abuse/revenge angle. The washing machine, symbolic of all parental torture…holding us to ransom, violently adopting a human 'clonic' fit of death; it’s final moments sullied by spewing it’s guts out.
A friend of mine got a really long extension lead and put a microwave oven out in a field. Then they put a variety of items in it, the best being a grapfruit which destroyed the oven and blew the door 30ft across the field.
