I always seem to recall that any sitcom seasonal special back when I was a kid would feature an incident where the turkey would never cook because someone forgot to turn the oven on or such thing.
This Christmas Special is not much different, no spare fuse wire when the Christmas lights blow the electricity, but then builds upon it with Cissie's presents which was nicely done.
Until then Cissie shows that she should not be anywhere around superglue as she tries to fix the nativity animals and becomes stuck. Also practicing Christmas Carols for the church proves a note too far for Cissie.
This is a well structured festive episode but I found it only mildly amusing but great interplay between the characters.
