William Shakespeare once wrote that "revenge is a dish, best served cold."

If so, Dierks Bentley may want to watch his back throughout his upcoming Sounds of Summer tour.

Earlier in the year, Bentley pranked tourmates Kip Moore, Maddie & Tae and Canaan Smith into taking the "polar bear plunge" on December 31st. Moore has always gained his revenge on the tour's headliner, redecorating Bentley's prized truck, complete with a billy goat.
