Borland is slightly overweight, and always seen wearing flannel, which Tim cracks jokes about consistently. He wears flannel so often that, in the wedding episode, Tim bets his friends that Al is wearing a flannel thong. The reason he always wears flannel came from his father, who, when asking young Al to assist in their own various home projects, would put his old flannels on Al to keep him clean or warm. Al wears flannel as a tribute to him after he died.
