Grampa Johnson

Oliver "Swede" Johnson is Alice's father and Dennis' grandfather.

Bio
Alice's father, who spoils Dennis often. He evokes the unintentional jealousy of Mr. Wilson, for he gets to see Dennis only on occasion, but Mr. Wilson sees him all the time. Because they are so much alike, Dennis and Grampa Johnson get along beautifully. Mr. Wilson also thinks that Johnson should act his age, but this advice is often ignored. To Grampa, life is worth living and he encourages Dennis to live it to the fullest. His wife's status is unknown; she is never seen in the comics, although she is mentioned once when, thanks to Dennis, a furious Alice finds out that Henry had thrown his mother-in-law's gift (a tie) into the trash.
