Came across this interesting blog article about artist Danny Quirk who specializes in scientific illustrations. I could say more, but better to show you some of his "work"...
On a more humorous note, take a look at this picture from Sports Illustrated ... As per the caption in SI , it is EXACTLY what it looks like except, A worker at Madame Tussaud’s puts the finishing touches to a model of Rafael Nadal in London last May. (Kirsty Wigglesworth/AP Photo) I did want to point out that though a screwdriver inserted into the ear canal may be OK for a wax model, it is not OK for a breathing, living human being.
