I've decided that perhaps I'm bulimic and just keep forgetting to purge.

Delivered in Poundstone’s characteristic self-deprecating, observational-comic voice, the line riffs on the language of eating disorders to describe ordinary overeating and guilt. The humor depends on incongruity: “bulimic” implies a serious clinical condition, but the punchline—“keep forgetting to purge”—reframes it as mere lack of follow-through, turning pathology into absent-mindedness. As a joke, it satirizes diet culture’s tendency to medicalize or dramatize everyday anxieties about food and body image, while also exposing how people sometimes use dark humor to manage shame or discomfort around eating.
