Most unique or unconventional marketing strategy

We ran a twitter bot, that posted memes everytime our competitor was mentioned on twitter. Had great conversions. Infact it turned out well for us and our competitors too..lol, ended up getting a lot of attention on twitter. The other time, I was marketing baby products on an ecom store and instead of regular fb ads and google ads, we went for pinterest ads. Worked very well, reason most middle aged woman spend most of their time on pinterest and are pretty loyal with it. Just a few. Cheers.
