Quote from Dr. Kelso in My Long Goodbye
J.D.: [v.o.] Others resorted to childish mischief. J.D.: I love mailbox baseball. Here comes his house. Turk: I've been wanting to do this for 6 years! [As Turk hits Dr. Kelso's mail box with a baseball bat, the structure stands firm. Turk is knocked off J.D.'s scooter and falls to the road.] Dr. Kelso: Nice try, Turkleton. But Enid kept taking out the mailbox with the motor-home, so I had it reinforced with titanium. [dings] Turk: Aah! Dr. Kelso: Beautiful morning.
