Hi Dagney. How ya doin?
As Punkofnice said "bad guys have all the fun" That is what it is about. The ghost of Christmas (Robbie Coltrane) shows Edmund Blackadder, a nice guy up to this point how bad his relatives where in the past. When Edmund see how they prospered by their bad behavior he decides that he has been a sucker being nice and becomes just plain nasty. It is hilarious. As MrJones5 said it is on youtube but I can loan it to you the next time I see you. I've got a copy that also has The Vicar of Dibley's Christmas special and that is also very funny.
