When I was very young, one of my mum's very good friends would come round to see us. Me and my sister liked him coming over as he liked to laugh and joke with us and we found him entertaining.
Sometimes he'd be sat on the sofa and we'd run up to him and grab his right leg nad he'd say to us "Careful now, that's my driving leg".
I was convinced that his leg was somehow special or fragile and we should be careful of it because he need it for this mysterious "driving".
It was only when I finally bought my first car 2 years ago (when I was 23) that I remembered and thought about this again and realised how much he'd been having me and my sister on.
