Must watch: John Oliver takes down Big Tobacco.

Last night, John Oliver laid a hilarious 18-minute smack-down on Big Tobacco!

The host of HBO’s Last Week Tonight rightly skewered Philip Morris International and other Big Tobacco companies for targeting kids around the world and bullying countries that try to save lives. And it was awesome.

He introduced a spoof tobacco-marketing character: Jeff the Diseased Lung. And talk of Jeff is already trending on Twitter and Facebook under the hashtag #JeffWeCan. So share the video and add your voice to the conversation!
