After 20 years of marriage, a Yemeni farmer divorced his wife and married his sister because of the Yemeni Qat (A plant found in Yemen which is chewed or drunk as a stimulant.)
The farmer works in cultivating Qat plants, and complained that his wife was too lazy in helping out with the farm work, and spent most her day chewing Qat and gossiping with her female friends.
He also explained that his wife's sister who is 25 years old, makes a better wife, she is not lazy, and knows how to cook. She also chews Qat with him while he is working to entertain him.
So he decided to divorce his first wife and married her sister.
