Trying to steer away from the standard tie-in-a-box gift for Dad this year? Take him to Wendy’s instead — you may even run into a star! Eva Longoria Parker made a surprise appearance at Wendy's for the second year in a row to kick off the franchise's annual "Father's Day Frosty Weekend," which benefits the Dave Thomas Foundation for Adoption. On June 20 and June 21, 50 cents from every Frosty sold will go toward the fast-food founder’s foundation to support its efforts to increase the number of adoptions in North America. If that’s not enough, additional funds are being raised through frostycard.com, where consumers can go online and send a free celebrity designed e-card to a special father in their life or design one of their own. Celebs who have designed for the cause: Eva Longoria Parker, Mario Lopez and Patti LaBelle!
