He jokingly said to his brothers, "I will exchange my wife." Does divorce occur?

If a husband jokingly says to his wife, "I will exchange my wife," no divorce occurs by that; because it is among the allusions to divorce, by which divorce does not occur except with intention and purpose. So if he did not have the intention of divorce, then nothing results from his statement. It is advised to avoid joking about serious marital matters like divorce.
