1. Let's say you get home from riding the Dash in Boulder and your pants are sopping wet, and your ankles are getting cold. You need to take off your pants at the door.
2. Let's say on your way to your room to put on some non-wet pants, you get distracted by the kitchen, get some ice cream, and decided to eat it while watching television, and incidentally discover the joy of not wearing pants and eating ice cream.
A dream is born!
