If you want to see a larger version of the examples shown in panels two and three, it can be seen in the sketchbook.
I know there's no experiment, but this is the second most requested myth and I thought of a strip for it, so here we are.
I considered many final lines for the last panel, and settled on one that draws attention to the subjectivity of attraction and how different people like different things. I had actually wanted to include that point somewhere before panel four, but there wasn't room for it.
Personally, the idea of a modest weight gain ray has some potential appeal to me, particularly if combined with a supermodel convention. A ray that would result in unhealthy obesity holds less appeal for me. I myself am overweight, and a transformation that results in an unhealthy, tiring condition doesn't seem as fun as others (though I obviously believe there are exceptions).
There are a lot of people, however, who really would like to see a fat ray and the subsequent plumpness that would result. It's not my cup of tea, but as the comic says, it's all subjective and to each their own.
