Got a teen who's over dressing up for Halloween? Inspire him by appealing to his favored qualities: sarcasm and irony. Suggest dressing up as a "cereal killer" (complete with butchered boxes of Cheerios), a "drag queen" (pulling a cardboard Queen Elizabeth behind) or a "Freudian slip" (dressed in a slip covered with words like "id" and "ego"). Who knows? He might even admit that your ideas are punny!
