I find them to be the weirdest thing on TV. I suppose people do have serious medical issues and they're desperate for any suggestion to help them, but the disclosure requirements (a good thing!) would make me not want to take any of these things. "May cause anal leakage, suicidal thoughts, homicidal thoughts, seizures, migraines, incurable insanity, limb detachment, incurable athlete's foot, heart attack, stroke, lycanthropism...." really don't sell these things, do they?
