My favorite so far is using the clip with two old women:
My idea is that the two women have just died and are at the pearly gates, recounting how they've spent their lives. The woman in back says a little too much information, they argue, etc. I think it could be fun to add the stress of constantly being watched by St. Peter behind the podium and trying to be on their best behavior.
(Still not sure how I'd like to compose the shot. If you have any suggestions, that would be great)
Just in case, my backup idea is using the awesome Christopher Plummer dialogue:
The shot would be of Santa talking to an elf in a breakroom at the north pole, telling him a story of a terrible christmas party he was forced into going to:
