My dad actually did something similar. Idiot. It was one of those machines that you use to tone up your muscles with small jolts. He was sat happily with them on his stompach twitching away and decided to turn it from setting 1 to 5. He was pratically climbing the wall! It was as though he was pinned to the wall and couldn't move to switch it off or shout for help. His fiance told me she found him totally flattened against the wall, standing on the couch and didn't know how long he'd been there for.
So what I read these jokes I laugh because I know that they're probably true stories. These people do exist.
Luckily for me I take after my mum
