Bill lives next door to the Burton family, and he is obsessed with his garden. He is always competing with Mr. Burton over whose garden is better. He was furious when Mr. Burton won the annual garden show and was determined to ensure that it wouldn't happen again.
Joe reveals that while Bill was mean to him and Mindy, Bill and Mr. Burton got along fine, and were always kidding each other about their gardens; when Bill looked up from pruning his shrubs to see Mr. Burton, Joe and Mindy coming back from a visit to Lawn Lovely with the gnomes Hap and Chip, Bill asked Mr. Burton if he got more lawn ornaments and chuckled a little.
When bad things started happening to his garden, he was quick to blame the Burtons' dog, Buster, as the one who is always getting into his garden. However, he eventually starts blaming Joe. He started to get blamed as well, but he denied it; it got to the point where he forbade his son Moose from seeing Joe.
He never discovered who was sabotaging his garden, nor is it known how he acted when the mischief stopped once Mr. Burton's lawn gnomes mysteriously disappeared one morning.
In the television episode, he is turned into a lawn gnome by Hap after he tries to get rid of them. He ends up being discovered by the judges in the Burton's garden, causing them to be denied the blue ribbon.
Bill is retired from the army, so he's used to giving orders and having them followed. He's very easily angered, especially when bad things happen to his garden. He is constantly arguing with Mr. Burton and making fun of his garden (although Joe says that Bill and his dad get along fine and are usually kidding each other about their gardens).
The television episode has him embracing his army past more, as he acts military-like when he orders Joe to fix up his garden. He also acts more abrasive in general, such as when he takes Joe's baseball when it lands in his yard.
Mr. McCall is only described as being "big," to the point where he makes his son "look like a shrimp."
