People do some daft things!. I remember a friend of mine, just qualified as a doctor, doing shifts at local A&E. ~A chap came in,walking horribly and in great pain. When she eventually saw him she had to gently remove - a milk bottle! Honestly!
One of my daughters (a doctor) worked A&E both in the UK and Sydney Aus. Apparently removing objects people "have fallen on" is a regular occurrence. In both countries.
