After saying that Lilith (Bebe Neuwirth) will be spending Thanksgiving with a colleague in Vancouver, Frasier (Kelsey Grammer) wonders aloud whether Canadians celebrate Thanksgiving. Although Canada does in fact celebrate a Thanksgiving, Canadian Thanksgiving is the second Monday of October.
The title is similar to "The Parent Trap" (1961 starring Haley Mills and 1998 starring Lindsey Lohan). In both versions of the story, the children conspire to reunite divorced parents, as Freddie appears to try to do here.
The video game played by Freddy (Trevor Einhorn), later by Niles (David Hyde Pierce), and briefly by Lilith (Bebe Neuwirth) is evidently on the original PlayStation. The controller is a late-model original DualShock with thumbsticks.
Frasier (Kelsey Grammer), anxious to have Lilith (Bebe Neuwirth) on her way, says, "Oh, now, nobody ever got anything from a rat that wasn't resolved in a day or two." Frasier, of course, refers facetiously to the Black Death of the 1340s, one of the deadliest pandemics in human history, widely thought to have been Bubonic Plague. Its rapid spread was attributed to fleas carried by rats. The total number of deaths worldwide is estimated at 75 million people.
This is the second episode that revolves around Thanksgiving, with Lillith and Freddie appearing together again. However, events occur in Seattle rather than Boston ("A Lilith Thanksgiving"). Also, Roz only appears in one scene.
