Best headline you have ever seen in direct marketing, advertising or sales

There is an answers area on Linkedin, where Boyd asked the question

" What is the best headline you have ever seen in direct marketing advertising or sales letters?"

His answer is "Lose Your Piles In Seven Days For Seven Dollars - Or Keep Your Seven Dollars And Keep Your Piles - Guaranteed!"

Personally, I saw this headline in my local newspaper under the dating ads section, and thought it was highly appropriate. (not that I'm looking for a date)

"Wanted: Safe Men For Dangerous Times"

I am sure there are many of you that have better than this.
