A new study in The New England Journal of Medicine finds that people can be bribed to quit smoking.

Different groups of subjects were paid differing amounts of money by their employers -- the highest amount being $750 -- to stop smoking for 90 days. The result? Using money as an incentive makes people three times more likely to quit, and three times more likely to continue not smoking after 90 days.

Long ago when Clark was in the travel business, he used a similar tactic to help his employees give up smoking. The penny-pincher offered a warehouse club shopping spree of $200 if they could kick the habit for 90 days. That would be equivalent to $600 with inflation today.

Clark himself managed to quit smoking two packs a day back in the 1970s by using his own unique aversion strategy. Whenever he wanted a cigarette, he would smoke a giant cigar. Within a few days, he no longer had any cravings at all!

The consumer champ has now agreed to pay his HLN cameraman Jack $750 if he can stop smoking for 90 days. We'll let you know how it goes!
