Tonight USA Network presents two mystery-comedy Christmas specials.

At 9 EST (repeated at 12 a.m.), is the annual Monk Christmas special. The comedy-mystery program is a limted series appearing in two sets of episodes per year, in summer and midwinter, so USA Network wisely presents a Christmas episode each year to help sustain viewers’ interest during the long layoff.

The USA Network describes tonight’s episode, "The Man Who Shot Santa," as follows: "Monk becomes a social pariah when he shoots a man dressed as Santa Claus. Can he clear his name and foil a larger criminal plot in time for Christmas?"

After Monk, at 10 EST (repeated at 1 a.m.), is the first-ever Psych Christmas episode. USA Network describes it thus: "The scoop: Christmas with the Gusters is ruined when evidence in a murder case leads the police right to Gus’ dad. Phylicia Rashad and Ernie Hudson guest star as the Gusters in the premiere of ‘Gus’ Dad May Have Killed an Old Guy‘!"

Those who enjoy mysteries, comedy, and Advent, will definitely want to watch these.
