My name's Kazza and I'm an injured sibling
In a house of three sisters we were constantly trying to 'off' each other for our own amusement and as a result tales of injury - physical and mental trip only too easily from my brain. Here are a few

My little sister once got me to climb into a laundy basket (one of those ali baba ones) and then put the lid on and sat on it. For a long time.
We used to get my little sister to sit in a dolls pram and then push her downstairs. It was alright, she used to stop when she hit the door at the bottom.
One of my sisters, still don't know who, put my prized speak and spell in the sink and ran water on it. Why??? And then left it there for me to find.
Another one of my little sister's master works. We never got bought many treats as kids - our parents were pretty badly off as my dad worked on the 'scaffy' (dustbin round). My mum bought me a covered alice band (this was the 80s mind you). My sister snapped it in half and then attempted to diguise the crime by flushing it down the toilet, as I discovered when I found it in the pan some time later.
My older sister had a dart thrown at her head (this one is the ice cream van chimes of this question isn't it). Although come to think of it, it might have been my uncle who did that and then blamed it on one of us...
When I was about five and my sister was four, she tried to sharpen my fingers(!!) with a Ronald McDonald pencil sharpener. With predictable results. One of my first memories that. Shortly after that she tried to bite off one of my nipples in a fight. How does a four year old think of that??!
To cap it all, both my sisters spent the first ten years of my life telling me that my parents weren't my real mum and dad (they are..I think).
The worst one was when I was 17 my sister told me my mum and dad aren't even married and she'd known 'for years'. Well didn't you wonder where the wedding photos were? Turns out I really am a bastard.

Ah, we were poor but we were miserable.
