SW definitely has the most developed sense of humor. One time I flew to LAX on SW. As we approached the airport over the countless lights of LA, the steward reminded us, "I used to live in LA, and my ex-wife still lives here in our old house. Those of you on the left side of the aircraft can see that she left the porch light on for us just over there."
After the plane landed it bumped along toward the gate, pausing several times, for over 15 minutes. Just before we reached the gate, the same steward announced, "We'll be stopping by McDonald's on our way to the gate so please have exact change as we come through the cabin to take your orders." People were still chuckling as we left the plane!
