J.D.: What should I do?
J.D.'s Narration: That was a huge mistake. Because the closer Turk and Carla got to their wedding, the more they became one of those annoying couples that thought they knew everything about relationships.
Turk/Carla: Look, J.D...
Turk: You first, honey.
Carla: J.D., love is like a butterfly. Hold it too tight and... you'll crush it.
Turk: Too loose and it flies away.
