Introductions
It is a cliche universally acknowledged that you only get one chance to make a first impression. Had I borne that in mind, it's possible I might have been able to conjure a better opening conversational gambit than "Ah. I thought you were a woman."

Well DONE, iMark! Nice to know you're as subject to foot-in-mouth disease as the rest of us. The only worse fate I can imagine is if your comment was followed by the rejoinder, "Actually, I am". Bravo, bravo :)
