Boucq is right on the money with this story. The first half is about a pair of chairs in a laundromat meeting each other, claiming to be reincarnated kings and generals. Here, he throws another take at reincarnation.

The man answers an ad in a newspaper about swingers and brings his wife – who is now a praying mantis. Of course the praying mantis eats the man after having sex with him.

The outfits that the swinger couple are wearing are great. :Leather vest AND medallion.
