Introduction
The ladder theory is a funny, scientific explanation of how men and women are attracted to each other. It also covers such topics as why women sometimes just want to be friends but men always want sex. It is based upon many years of sociological field testing, and was first conceptualized in 1994 in Exeter, CA by Dallas Lynn with acknowledgements to Jared Whitson for his role in formalizing the theory.

Sally: We are just going to be friends, OK?
Harry: Great, friends. Itâs the best thingâĶYou realize, of course, that we can never be friends.
Sally: Why not?
Harry: What Iâm saying is - and this is not a come-on in any way, shape, or form - is that men and women canât be friends, because the sex part always gets in the way.
Sally: Thatâs not true. I have a number of men friends and there is no sex involved.
Harry: No, you donât.
Sally: Yes, I do.
Harry: No, you donât.
Sally: Yes, I do.
Harry: You only think you do.
Sally: Youâre saying Iâm having sex with these men without my knowledge?
Harry: No, what Iâm saying is they all want to have sex with you.
Sally: They do not.
Harry: Do too.
Sally: They do not.
Harry: Do too.
Sally: How do you know?
Harry: Because no man can be friends with a woman that he finds attractive. He always wants to have sex with her.
Sally: So youâre saying that a man can be friends with a woman he finds unattractive.
Harry: No, you pretty much want to nail them, too.
Sally: What if they donât want to have sex with you?
Harry: Doesnât matter, because the sex thing is already out there, so the friendship is ultimately doomed, and that is the end of the story.
