I can't say I'd heard of McMansions before this and The Simpsons, either.
Anyway, it was all right; not their greatest though, mainly because the court room climax didn't really have any tension. You pretty much knew Hank and the gang would get off scott free.
I liked Khan getting psyched that Ted Wassanasong might be moving next door, and whose world crumbles when he finds out he isn't. The observations regarding the house blocking the sun were funny ("I can't tell if the burgers are cooked!"; "My body is weak from lack of sun"). And I did like the end of the second act when the neighborhood had to demolish the house; the storm gave them a legitimate excuse to destroy that eyesore.
