Finally remembered a non-car-related one
I was about 6. We were at my grandparents house. I cant remember whether we were staying there, or elsewhere, but I know the usual "kids" room was off-limits (as was the rest of the top floor).

Where was I? The top floor. Mucking about. My sister called me downstairs. I thought, "What's the best way to get downstairs? I'll slide down the banister". Now, this banister was tempting, given the floors it passed through, so I hitched a leg over, and started my descent.

So far as we can work out, I made it to the first corner. There, apparently, I slipped straight into the gap between opposite flights, knocked myself out on the stairs, and dropped straight down, between the flights, to land in a heap at my sisters feet, head first.

Obviously, my arrival was a little quicker than my sister had expected, and a little more violent, so she went to the sitting room to explain, to my parents and grandparents, that her brother had just arrived suddenly at her feet. *They didn't believe her*

Apparently, they only came out into the hall to inspect the damage once I started coming round, and started making a lot of noise.

I managed to get a fairly bad concusion from that one, but was convinced for years that I had only fallen down three steps...
