That's all inside baseball to me. Here's one of my favorite jokes if you want to think some more on what I've pointed out.

A man comes home and hears noise from the upstairs bedroom. He walks upstairs and opens the door to his bedroom where he sees his wife in bed, looking a bit exercised. He starts looking around the room for another man and finally opens the closet door. He finds his best friend Sam. "Sam, what are you doing where." "Well," Sam replied, "You know, everyone has to be somewhere."
