Frasier (Kelsey Grammer) agrees to cover for KACL's "gonzo" sportscaster, Bulldog (guest star Dan Butler), on Christmas Day. Frasier hopes the working holiday will take his mind off of his disappointment that his son won't be with him for the holiday. Instead he faces a long day of being "hum-bugged" by callers whose stories would depress Charles Dickens. Mel Brooks, Eric Stoltz, Ben Stiller, Rosemary Clooney ("This Old House"), author Dominick Dunne ("Another City, Not My Own") provide the voices of callers to Dr. Crane's radio program.
