Sam Seder (It Snakes a Village)
Al (also known as Grandpa Al or Gramps by his grandchildren) is Linda and Gayle's father, Bob's father-in-law, and the grandfather of Tina Belcher, Gene Belcher, and Louise Belcher. He is married to Gloria.
In Crawl Space, Al rarely speaks and seems relatively happy. Gloria often speaks on his behalf and he follows her orders.
In It Snakes a Village, he is now voiced by Sam Seder and has a slightly grumpy attitude towards Gloria being startled by loud noises as he has a balloon fetish where he likes to watch women inflate balloons and pop them by sitting on them. Bob counteracts this by giving Gloria ear defenders.
Al has a number of health conditions often associated with advancing age including hearing loss in his right ear for which he uses a hearing aid and has problems with his heart, liver and one of his kidneys. He also has leg pains and dry mouth.
