On second thought, maybe one's enough.... The BBC reports:

Wife 'beheads husband' in Karachi 

Police in the Pakistani city of Karachi say a woman beheaded her husband and chopped up his body after he announced plans to take a fourth wife.

Officers said Majeeda Khatoon killed her husband while he was asleep and cut him up, helped by two male relatives.

The dismembered parts were then dumped in a drain in the Gulshan—e—Hadeed area on the city's outskirts.

Police said the woman, arrested last week, had confessed to the crime. Islam permits men to take up to four wives.
