The problem is certain women’s increase in physical attractiveness has been disproportional to their increase in psychosis. Luckily for us, a chart exists where we can see just how out of balance the ratio between your hotness and craziness has become - knowledge that can prove to be invaluable over the course of your daily life.

The scale is a scale is with the vertical axis labeled "HOT" and the horizontal axis labeled "CRAZY."

A girl is allowed to be crazy, as long as she is equally hot.

If shes crazy she has to be hot, if shes really crazy she has to be really hot.

As long as a girl is above the “Vickie Mendoza Diagonal” she is approved for dating. Vickie Mendoza, a girl Barney Stinson from How I Met Your Mother dated, she played jump rope with that line. This diagonal is a reference to the Mendoza Line in Baseball.

If a female becomes to crazy without becoming hotter, she may drift extremely close to the Shelly Galezby Zone.
Barney: A girl is allowed to be crazy as long as she is equally hot. Thus, if she's *this* crazy, she has to be *this* hot. You want the girl to be above this line on the Hot-Crazy Scale. Also known as the 'Vickie Mendoza Diagonal'. This girl I dated. She played jump rope with that line. She'd shave her head, then lose 10 pounds. She'd stab me with a fork, then get a boob job.

Barney: I should give her a call

Adam: Well, I've been trying to hit it but she keeps drifting across the Mendoza Diagonal. She is getting extremely close to the Shelly Galezby Zone on the Hot-Crazy Scale.
