Clancy is an teenage boy with glasses. He has a red shirt and blue jeans. His shoes are brown with brown laces. His favorite food is tacos as stated in his Flipdeck. His orders are normally very simple, and whenever possible, they involve large amounts of vegetables like peppers and jalapenos. He also loves hot sauce, because he is unlocked with in in Hot Doggeria and Burgeria HD. And he also seems to like strawberries, since he orders this in Freezeria and Pancakeria . He is one of the customers to never be absent in any of the Gamerias, but was not absent in Papa Duncan 2: When Burgers Attack!. He is Clancy's grandfather.

His favorite activities are playing video games such as Pac-Man, Donkey Kong 64 and Mario Kart. He was also one of the first purchasers of the G.I. Joe: Retaliation expansion pack in his original G.I. Joe Guts.

Like his younger brother, he doesn't want to retire like him anymore since he's gotten a better job during the past decade. He feels bad when he finds out because he has had such a hard life. He feels guilty too for how much he lost with his brother and wants him and his family to live off their earnings (to make a profit on his own).
