Dale had been estranged from his father, Bug Gribble, since he witnessed Bug talking to his wife Nancy, because he was trying to conquer his fear of man-ladies. He had to basically raise himself with a TV. He always watched History Channel, that is why he believes in conspiracy theories, owning guns, and hunts criminals.
Role in The Great Pumkin War
During The Great Pumkin War, Dale was imprisoned for helping Hank Hill in the rebel army. Dale was released by Hank along with the other rebel leaders. He helped storm Butter-O-Mart and helped take back Arlen.
Today Dale lives a relaxed, laid back life. He has taken a part time job at History Channel solving conspiracy theories on his show, Truth or Dale. Unfortunately, he doesn't make much from this, so he still exterminates bugs and he still tracks down criminals. After that he met up with Hank Hill again to get Real Pie from a McDonald's, but it turned out it was just Pie and he asploded in 2014. After his funeral a monument was built to remember his contributions to the war effort.
