|Behind the scenes|
|Voiced by|| H. Jon Benjamin ("Crawl Space")|
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 maternal grandfather of Tina Belcher, Gene Belcher, and Louise Belcher. He is married to Gloria.
]Al is an elderly man with grey hair. He is shorter than his wife and Linda. In his first appearance, he wears a high-waisted tan pant with a light blue shirt. He wears a hearing-aid and glasses.
In Crawl Space, Al rarely speaks and seems absent-minded. 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.
