I have a friend who lives really close to my house. I like him a lot, but he's got some really weird habits.
He demands that I take him out to dinner pretty frequently—once or twice a week, it feels like. He likes to go to this one place that serves really, really greasy food. Like, I can't even eat it, it's that bad. He eats a hell of a lot, too; the food is actually pretty cheap, but the bill usually comes out to around $30! No wonder he weighs over 300 pounds.
He spends a lot of time outside, even in freezing cold weather; he doesn't seem to mind the cold at all. He really enjoys running, and he's surprisingly fast for such a big guy! He could easily outrun me any day of the week.
He only takes a shower with soap about once a week, if that. Disgusting, right?
But all in all, he's a really good friend, and I wouldn't give him up for ten thousand dollars.
Who is he?
