After Bruce (Jack Black) asks the kids, "Am I getting through to you!?" the camera goes onto Chloe who says, "I'll never do drugs, ever!" and the camera pans to the right, and shows Preston, who says, "Drugs are evil, do you hear me, evil!" So meaning that facing the audience, Chloe is on the left, and Preston is on the right, but when the shot changes, and is wider, they switch spots.
Where's Tanner's dog? Did Lesley manage to get rid of it, because it's not in the guest house, because Lesley and Ted were there, and Ben didn't seem concerned about them finding him. And also, it couldn't be in the house, because most likely, the drug dog would've found Tanner's dog, or Tanner's dog would have come running out to see the other dog.
Ted: ...we can get high on other things, right kids?
Chole: Yeah, like cheerleading.
Preston: Or basketball.
Tanner: Or videogames.
Ben: Or pizza.
(Ted, Lesley, and Ben stuff pizza in their mouths)
