I sat next to Hitler in third grade and beat him up for his lunch money all the time!
— Grandpa
Grandpa Pearson (first name unknown) is a supporting character in Edward and Eric. He is the father of Paul, the husband of Grandma Pearson, and the grandfather of Edward and Eric. He is voiced by Dan Castellaneta.


Grandpa is a good-natured, optimistic and humorous grandfather who always brings something new to the table. He loves his family members all the same and enjoys fun as much as the Pearson brothers. In his spare time, he likes to watch TV, read the newspaper, sleep, tell false stories that stem from his bad memory, eat prunes and jello, play golf, discuss "the old days", and listen to corny old songs on his phonograph.


  • Grandpa being voiced by Dan Castellaneta is an Actor Allusion at how he voices Abe Simpson from The Simpsons and Grandpa Phil from Hey Arnold, both of whom are also grandfathers.
