What is the stupidest thing you've done as an adult?

{@andys ] at work at a hospital this was over thirty seven years ago the hospital was closed our department stayed. me and my college thought it would be a good idea to burn some old clothes inside an old fridge i went to poke the stuff we where burning against the advice of my college. when the fridge blew and knocked me back on my arse the thing of the back of the fridge blew . i can see the funny side now but i could of been badly hurt or killed that day .
