Elbow Patch of Power

It's long been a cliche that teachers and lecturers have elbow patches on their jackets. A sort of boring man's badge of honour. I've not had elbow patches before, but they've kind of become retro-chic now, so I bought this John Rocha jacket yesterday in the sales complete with elbow patch. I feel it will convey me with superpowers: The Elbow Patch of Awesome Sagacity!

PS - it is retro-chic isn't it?
