Join or Die with Craig Ferguson - Season 1 Episode 2

On the topic of History's Worst Medical Advice, the six items up for consideration between Craig and the panelists – Bob Pflugfelder, also known as "Science Bob", and comedians Jordan Carlos and Chris Hardwick – are: smoking is good for you; bloodletting (specifically by leeches) is a cure-all; lobotomies cure mental illness; pulling teeth helps combat depression; the use of mercury can cure a variety of maladies; and drinking one's own urine can purify the body. Beyond the merits of keeping the issue on the list, they talk about which ones are still being done in some form (if even recreationally), the rationale behind the logic of the act, the veracity of each by renowned scientists during their time, and the role religion, metaphysics and faith play in health. Bob does a show and tell of historic unusual medical devices. They also discuss other treatments not on the list and the association of the six to other things people do to their bodies.
