Hm.... i am genius, therefore i shouldn't be wearing pants..... but it is extremely cold.... If i don't wear pants, i will get sick. It wouldn't be very smart at all to get sick because "geniuses don't wear pants"...... Therefore it is currently impossible to not wear pants AND be a genius.
*shrug* on the other hand, GENIUSES DON'T WEAR PANTS
The phrase "geniuses don't need pants" only refers to a lack of pants. However, skirts and shorts aren't considered pants. Many idiots are still wearing shorts in December. They are obviously being a little stupid by doing so in below freezing weather, but because they aren't wearing pants, they would be considered geniuses.
