The Great Houdini had an interesting encounter with an Oregon Boot. He appeared at the San Francisco Orpheum Theatre during 1922, and the management offered a $500 reward to anyone who could produce a handcuff from which Houdini could not escape. One evening a policeman in the audience brought an Oregon Boot to the stage. Houdini protested that it was not a handcuff, but the audience chided him to wear it along with a variety of handcuffs. The Great Houdini stepped behind his protective screen, and a few minutes later the removed boot and handcuffs were tossed out to the audience.
BTW: :-P
