Stealth butt plugs and predigital dildonics of yesteryear

The Museum of Quackery is an interesting place. In their online collection, you'll find "The Recto Rotor," once touted as "The Latest and Most Efficient Invention for the Quick Relief of Piles, Constipation, and Prostate Trouble," and a "prostate gland warmer" which promised to "stimulate the abdominal brain." The latter consisted of a 4.25", um, probe, and a blue lightbulb on a 9' cord which lit up when, um, plugged in.
