Jay Alexander is a real model trainer, but on some of these other TV/model shows, I see non-descript gay guys yelling at models backstage.
How do I get that job?

Even on the Missy show and making the band, they always find some loud mouth to yell at people and get them moving. Do these people actually exist in show business?

God! I have done that. Models are like cows. You have to prod them until they move. Thickest beings I have ever encountered. Any straight guy fawning over models does not how good it is at home, with the mrs. Models suck. But the wrong things.
