Motivated, the men go outside to start persuading people to sign the petition. The next day, the two men come back to the manager of the campaign.

How did you do it?"" The man shows him [this](http://i.imgur.com/M5tvTCE.jpg) picture, to which manager replies, ""Nice thinking!""

So the man replied, ""I first told them if they used drugs, they would get arrested, then i showed them [this](http://i.imgur.com/VbQs2Xc.jpg) picture."" source:the interwebz sorry i forgot.
