It's been a tough news week, let's end it on a butter note. Thieves in Guelph, Ontario—but not just in Guelph, Ontario—have been stealing hundreds of pounds of butter from grocery stores, making off with about $1,000 worth of the yellow gold with each successive heist. It's been happening for months, and the only people police managed to charge so far ... have vanished.

So why butter? Why so MUCH butter? What do you even do with a hundred pounds of butter at a time? Who's buying it and what are they using it for? And why, with so much evidence and such brazen thefts, have police not been able to stop it?
