Meg: Mom, can I turn the heat up? Lois: Don't touch the thermostat, Meg. Your father gets upset. Meg: Come on. This thing goes up to 90. [Meg adjusts it a little, and Peter suddenly comes into the room] Peter: Who touched the thermostat? Meg: God, how does he always know? Peter: Brain implant, Meg. Every father's got one. Tells you when the kids mess with the dial. Guy: My thing went off! Your thermostat okay?
