OK, my career as a jingle writer may be in some trouble. But the point is, go to Facebook and become a fan of Libby vegetables, then fill out the form and they'll mail you a coupon for a free can of veggies! (You won't see anything until you click Like, but don't be alarmed.)
Looks like they're having a little problem with their online form, but the offer is good through May 15, so you can come back and try again if you're having trouble.
