On This Day in History, May 31:

1678 Lady Godiva rode naked through the streets of  Conventry protesting taxes.  

This is really Lady Godiva.  Really!  (this is one of the pictures when I Googled Lady Godiva)

And on the exact same day and place Peeping Tom also became a household word.

According to Wikipedia:

Peeping Tom is a nickname commonly given to voyeurs, particularly males. It originated with the legend of Lady Godiva, when a man named Tom watched her during her nude ride and was struck blind or dead.
