I came back from the post office yesterday and realised I was wearing my trousers inside out.
Easily done!!
I remember giving a presentation a very famous cancer research scientist years ago with my work, this guy was super bright, well respected in the scientific community, but wasn't that great at day to day stuff.
At the end of he meeting I noticed he was wearing a jacket that stull had a wire cothanger inside it- the curved wire hook was sticking out the top of his hjacket and pressing against the inside of his neck.
This guy was leading a team of 300 research scientists!
