Despite lifelong belittlement by his own father, Homer deeply loves and is intensely devoted to his wife and kids, when it occurs to him. Thus, Lisa feels left out, Bat acts out, and as far as Homer is concerned, Maggie rarely even exists. As for Marge, Homer often sings her praises - between rounds of beer at Moe's Tavern. Now, if only he could remember the words to that praise-song. Homer is a man who, through punishing trial and error, has proven that even one's loftiest goals are attainable. Provided you set them low enough and assuming they include donuts. He is also well versed in the ins and outs of his job at the Springfield Nuclear Power Plant, having been fired and rehired repeatedly for the same position.
