7700 tonnes. Of weed. As reported by the Center for Investigative Reporting, that's the amount of weed seized on the US-Mexico border from 2005-2011. So, a lot of weed.
The video above was made by the CIR, who, in a more detailed report their site, get fantastically nerdy about just how much weed we're talking about here. (Hint: a lot.)
For some reason, they've based the whole video on the "All Your Base Are Belong To Us" video-game meme. Because of course they have.
