I've done some stupid things.. I've forgotten most of them but a few recollections include.
1) Sticking my finger in a live lamp socket and getting hit with 240 volts when I was 9. I knew what would happen but did it anyway.
2) Trying to open a container with a pair of scissors and puncturing right though the flesh between my right thumb and fingers. That stung a bit.
3) Setting fire to the gas taps in a chemistry lesson. Oh, and making a mercury thermometer explode too.
4) Breaking a toe on a door getting up to take a p*** in the night. Ouch.
5) Driving at 135mph in heavy rain. I'll not mention where but it was a long time ago and rather stupid.
6) Breaking both my arms at once falling over.
7) Snorted coke. I mean Coca Cola not Cocaine. Ever wondered what it's like to burn you nostril hairs out?
Stupid is as stupid does...
