Snake oil vendors.

I used to watch old westerns and when they'd show one of the old timey snake oil salesmen, I'd think to myself, "Wow, I'm glad people aren't as misinformed and gullible as they used to be."

Unfortunately, later in life, I found that not much had really changed except the packaging and the credentials of some of the peddlers.

Thank you Dr. Oz and others that keep misinformed, desperate people stuck in old timey ways of thinking.
