At one point, Tim mentions that his father died when Tim was just a kid. However, Tim Allen's real-life father also died in a car accident when he was just 11, which is roughly around the same age as his character was when his father died. Perhaps Tim Allen wanted to bring the loss of his father into the show by having the character have experienced the same thing.
The title is based on the common expression: "Where there's a will, there's a way."
