"My bestfriend proposed to his girlfriend last week with a 10-story college dormitory . . .There were about 10 of us helping him out. When he stopped her in the middle of the parking lot, he gave his speech and we all waited for the signal. When he got down on one knee, we turned each floor on in descending order with a person in the stairwell shouting to each floor when to turn their lights on."
