Jack's Dad is married to Jack's Mom. He works in the daytime and almost always wears a tie. As seen in the panel comics, he enjoys to go fishing on his days off, and tries to cook meals when Mom is not home. His cooking is not known to be good.
He has a similar appearance to his son, Jack, except that his hair is smooth, like the old style Jack and not spikey. He also has the iconic family feature on males, which is two strands of hair sticking up on the back of his head.
