Technically, Bush didn't lie. During the campaign, whenever reporters pressed him on the question of whether or not he ever took potty breaks, he always deftly changed the subject. This, of course, prompted John Kerry to claim that he had to pee frequently and was immensely proud of the fact. However, many of the men he served with in Vietnam claimed that he had never actually been seen using the latrine in the entire time he was there.
Bush can pee farther than Kerry.
