Say Cheese

I've seen this video quite a few times, in different iterations, at different points of time. I don't know what it is, but I can't help but laugh every time. Two props that elevate it to share-worthy status: 1. It's about drugs. As a public health researcher (wannabe) specializing in drug policy, it's my duty to share such knowledge. 2. I believe heroin was what got my geometry teacher arrested, so this has special resonance.
