Abraham Jay-Jebediah Simpson II

Voiced by Dan Castellanata

Abraham Jay-Jebedaiah Simpson II, AKA Grampa, is a WWII veteran. He was in the army with Charles Montgomery Burns, which coincidentally, happens to be his son's Homer's boss. He was sent to the Springfield Retirement Castle by Homer, but is frequently shown in the Simpson Household. Homer tries to avoid Grampa, but shows feelings for him every now in then, (e.g.: Homer Simpson in: Kidney Trouble, where he is willing to undergo life-threatening surgery to save him.)
