That is, of course, the point of all comedy. We either make fun of someone else, or make fun of ourselves, or we make fun of the situation.
The situation here is so overblown that to me this person represents the situation itself.
This was pointed out particularly well by the Hindu fellow who said, “I want to live in a country where the poor people are fat!” That country could very well be where I live in California.
I used to weigh 240 pounds and now I only weigh 172. Anybody can lose weight because it’s all in the brain. Either you control your brain or your brain controls you.
The woman in the picture above clearly has the brain of the Dalmatian Molly Fish. They will eat until there’s nothing left.
I was really harsh in my earlier post regarding the picture, or was I? You could argue that the woman in the picture, for all we know, has a medical condition, which is why she's the size she is. That would make our attempt at humour bad taste.
You could also argue that she's like that because, like you said, she has the brain of a "dalmatian molly fish" and her size and miserableness, is that even a word, are completely down to her own very bad choices in life.
I'm going with the latter.
