So it's rare on TV and such to see shows that pair an obese woman with a thin, muscular, hot man. But it's pretty common (as Smallwife said) to see shows where an obese man is paired with a fit, hot wife. Starting with the Honeymooners back in the 50's, and now we've recently seen it in shows like King of Queens and Family Guy (which is a cartoon, I know, but still...). It's an odd thing. Usually if there's a fat wife in a show, she is also paired with a fat husband (Rosanne is a good example, although not recent).
I know TV is fiction and can't possibly reflect real life, but I see a double standard. I'm not saying the evil patriarchy has anything to do with it or anything like that, it's just an interesting thing I've noticed about our pop culture. That it's somehow more okay for a man to be fat than a woman.
To me, a fat man is just as unappealing as a fat woman. Some people seem to think that fat men are like "teddy bears" or are "more cuddly." I tend to disagree.
