The law firm of Hutson & Harris in Waco, Texas, makes YouTube videos to give people general legal advice. They've found that people respond more if that advice is in the form of a song. This one is about marijuana brownies.
See, putting pot in your brownie mix sparks a new violation under Texas law: the entire recipe is considered a controlled substance, so the weight of your brownie mix adds to the crime. A tiny amount of marijuana added to a pound of brownie mix will get you a felony charge. Take their advice, and don't do it in Texas. What you really want to do is check out their other videos, especially the one about medical malpractice lawsuits. Chris Harris stepped into the discussion at reddit to tell us some more about the brownie video.
