Quote from Lois in Reese's Job
Lois: Did you get it? Hal: Yes, I got it. Pet store owner said it was already dead, but I suspect the worst. Lois: Okay, we switch them tonight when Dewey's sleeping. Hal: Lois, it seems so sneaky and underhanded. What kind of example are we setting for the boys? Lois: Oh, Hal, stop worrying. The boys are fine.
