Mark: Thanks to Dr. Wilsonstein, I've turned my horrible family into zombies. Now I have the whole house to myself.
Heidi: Oh, Clark?
Mark: Well, almost to myself.
Heidi: More root beer?
Mark: Don't mind if I do.
Tim & Jill: Let me in. Let me in.
Tim: Let me in.
Ronny: Clark, parents.
Heidi: What are you gonna do about them, Clarkie?
Mark: I'll tell you what I'm going to do. It's time to say goodbye to them forever. [Mark and Heidi cackle]
