As a nurse I have had to care for men and all of their body parts. Would it be a joke if I made a comment on a man's private parts and if I had would he think it was funny and he should just say "thanks" to me? I respect 100% the patients that I have had to treat, I can say that most people are not comfortable with being nude and they feel vulnerable to be nude in front of a total stranger. I am very sensitive to the feelings of those who I care for and would no way embarrass them or make them uncomfortable by making a joke about their appearance. What is the disconnect with some of you that think it is ok to call a flight attendant  "sexy" who is doing a FAA required safety demo to the passengers on the plane as the plane prepares for all the safety checks to take off just a "joke".  No, that is not a good time to tell a "joke"  and you should have learned that at some point in your life. The man was kicked off the airplane and rightly so.
