Mercifully killing the ill-advised Mr. Wendy, Wendy’s is bringing back founder and long time spokesman Dave Thomas. No, he wasn’t found hanging out with Elvis in a nursing home, he really is dead. But, in an equally ill-advised and questionable effort, the chain will feature pictures of Dave Thomas in a new campaign, to debut Friday, touting the burger joint’s 35th anniversary. With slumping sales, Wendy’s needs all the help it can get. Who knows, maybe dead Dave can help.
