George: Sue's teacher, Brenda. She's... She's dead.
Tom: Oh. I better tell her.
George: No, no, no. I can do it. Sue?
George: You know your teacher, Miss Brenda?
George: She's dead!
George: Gone forever! Died a horrible, painful death! Gone, gone, gone, just like your dog!
Sue: My dog's dead?
George: I just ran him over with the car when I drove in! Everyone you love around you is dying!

When Cindy and the rapper guy are fighting the Ring girl, the president walks in and says, "I just want to wish you both good luck. We're all counting on you." and then he walks out.
