Niles and Daphne's baby is named David, after David Angell, one of the producers who was killed on the September 11,2001 attacks in the first plane to hit The World Trade Center (American Airlines Flight 11).
This was the only episode that had a rainbow in the opening title card.
The woman Frasier is telling his story to on the plane introduces herself as "Dr. Anne Ranberg", a melding of the names of series writing partners Anne Flett-Giordano and Chuck Ranberg.
When Roz tells Kenny to go on the air for Frasier, she tells him the last time she did it "it was a total disaster!" This is a callback to Enemy at the Gate (2002) when Roz let it slip on the air to a caller that she and Frasier had slept together.
It won an Emmy Award for Outstanding Multi-Camera Picture Editing for a Series.
