This takes me back to the late '70s when I was doing my PPL. There was one instructor who would take ages to come out to the aeroplane. I'd be sitting there for what seemd a lifetime after pre-flighting it. So one day I drew a little cartoon and gave it to him when he finally appeared.
It was of a C150 cockpit with the door open, a skeleton hunched over the controls, spider's webs in the corners of the doorframe...
It didn't make him appear any quicker for future lessons, but it made me feel a bit better.
