Jake Harper is the son Alan Harper, he lives with his uncle Charlie in his Malibu beach-house.
While Jake is a relatively nice young man, he's very lazy and unmotivated. He gets very low grades and spends most of his time eating food, or 'processing' it.
Jake does have some hobbies, he is a very good cook - although he's less good at not burning down the kitchen. He also plays the guitar. Despite these hobbies, he has started many expensive hobbies only to get bored and give-up, much to the chagrin of Alan, who must pay for the hobbies under the terms of his child support agreement.
