I was given the book "The 85 ways to Tie a Tie" as a gift many years ago. It is a wonderful read for nerds.

"Two physicists prove that there are not just four ways to tie a tie, but a further eighty-one. ‘The 85 Ways to Tie a Tie’ unravels the history of ties, the story of the discovery of the new knots and some very elegant mathematics in action."
