After the food fight you can hear Kelsey Grammer ( Frasier) say "good turkey...George" to George Wendt instead of his characters name, Norm. Which makes him laugh.
Vera appears for the only time but her face is covered with pie.
Before dinner, everyone mentions how they got to Carla's. Norm says he took I-93. Cliff mentions he took the back roads and Frasiertalks about using the Massachusetts Turnpike (also known as the Mass Pike). Woody mentions he took Boston Common, assuming he took the subway. Realistically, if Carla lived by the airport, these are the 4 main ways they would use to get to her house.
In 1997, the TV Guide ranked this episode number 7 on its "100 Greatest Episodes of All Time" list.
