That kid is responsible for the wholesome crappier lifestyle for the family and surroundings, with every investment you put into it going down the drain, as he will never amount to anything more than a sack of skin incapable of propelling itself forward. I guess there's some redeeming in the fact he didn't have to pay for college tuition fees, since that cripple won't be the next Stephen Hawking.
Good for the old man that he gets some exercise, but a weighted vest would've cost him less than $40 and saved him a lifetime of wiping and spongebathing some useless kids ass.
