Strking a blow for pregnant ladies

I hear stories from other ladies about some of the incredibly, unbelievably NASTY things coworkers were saying to them while they were pregnant (asking if they're having twins, making beeping sounds as they back up, etc.). I had shared this with John who was filled with righteous indignation. He got on a tirade of "if I ever hear anyone say anything like that about you or any woman I will (fill in appropriately amusing threat of a southern gentleman here)." Well, today he finally got his chance. One of our coworkers (a really nice guy who apparently left his good sense at the door that day) came up to him with the "I can't believe your wife still has 3 months to go - she looks ready to pop" comment. John explained to this guy, in no uncertain terms, that this was a completely unacceptable thing to say to ANY pregnant woman for ANY reason and that anyone who would say such a thing is showing not only his obviously crude upbringing, but also a gross lack of intelligence. The guy was apparently totally embarassed and went away as quickly as possible while the female coworkers in the area cheered.
