A misanthrope might be fun. It would be similar to grilled cheese because it would have one main goal, to be alone. He wouldn't have to be mean, but, of course, if he doesn't have a lot of nice points, he could be fun.
Put him in a big family and watch the fun.
Also, a jokester. You know, the kind who thinks he's funny, but isn't. Or he is funny, but h is humor is anger fulled so it turns people off.
