You must bee kidding

Drug dogs I can handle. Minesweeping dolphins, I can handle. But bomb-sniffing bees? Are you joking? Ok, I'm not arguing the capacity of the bee to smell gunpowder or C4. That's great. But seriously -- how many people can look at a bee and tell whether or not it's sticking its proboscis out? At some point science runs up against the wall of basic common sense.
