Gob: Didn't Dad teach us that we don't yell in this family?
[flashback to the Bluth kids screaming on the boat:]
J. Walter Weatherman: Tell me before you hit the gas.
George Sr.: I can't hear you! The kids are yelling.
J. Walter Weatherman: Tell me before you hit the gas.
George Sr.: I guess you're saying, "Hit the gas."
J. Walter Weatherman: Don't! Wait! [screams as the boat sets off and his arm is ripped off] No! That's why you don't yell.
