Revenge billboards are getting to be a trend. Expensive but emotionally satisfying, they're great for anything from declaring spousal inadequacies to calling out cheaters. This one, in Greensboro, N.C., goes the extra mile by spoofing MasterCard's "Priceless" campaign. It reads: "Michael – GPS tracker – $250, Nikon camera with zoom lens – $1600, Catching my LYING HUSBAND and buying this billboard with our investment account – Priceless. Tell Jessica you're moving in! – Jennifer." Chad Tucker of Fox 8 News broke this story.
