I was once asked to give a talk on 'sexual activity in married life' from a male perspective. When I arrived at the hall I was told that my time had to be limited as many other things were happening that day...I was told to make my talk as brief as possible.
I was introduced as the person who had come to talk to them about sex!
I rose from my seat at the appropriate time and coughed...and said..... "Ladies and Gentlemen...It gives me great pleasure...." Then I sat down again to roars of laughter.
I did give the talk of course!!!
