After his wife died, Mulla Nasrudin married a widow. But things did not go smoothly because Mulla constantly talked about his former wife and the woman constantly talked about her dead husband.
One night, lying in bed, they began to talk about their former spouses again, when sudenly Mulla shoved his wife off the bed. The woman was so upset about this incident that the next day she complained about Mulla to her father. The father-in-law asked Mulla why he had pushed his daughter off the bed. Mulla said:
Believe me, it was not my fault. With my former wife and her deceased husband, there were four of us in the bed, and there was not enough room, so she just fell off!
This spiritual story is from the book Classic Tales of Mulla Nasreddin by Houman Farzad.
