Not a joke!!

Polygamy is NOT a joke. Therefore polygamy "jokes" are not funny AND are incredibly disrespectful to your wife. If your wife knows of those 'jokes' and is hurt by it, it shows  how you do not care about her feelings. Not hurting your wife is a part of the sunnah.  I do not find polygamy jokes funny and I find it hard to respect men who make them. Have a little respect for yourself, your family and especially your wife. Do not hurt her. Thanks.
