Barker, who hosted the long-running game show for 35 years before stepping down, is an animal rights activist and is known for signing off with the plug, "Help control the pet population. Have your pets spayed or neutered." His successor, comedian Drew Carey, has continued the tradition.

In this first-look photo above, we see Carey welcoming the TV legend back to his old stomping grounds. Also, check out a sneak peek of Barker's return:
