In Frasier's first holiday episode, Frasier Crane (Kelsey Grammer) makes plans to spend Christmas with his son Frederick (remember him from Cheers?). But when these plans fall through, a disappointed Frasier volunteers to fill in for sports-show host Bulldog at radio station KACL on Christmas Day. Unfortunately, all of his callers are just as depressed as he is, leading Frasier to seek comfort after his gig by going to a diner he has never previously visited. Our hero's uncharacteristically shabby appearance and dour demeanor have an unusual effect on the diner's regular customers. ~ Hal Erickson, Rovi
