The leaping father is not encountered often, but exists. Two leaping fathers together in a room can cause accidents. The best idea is to chain heavy-duty truck tires to them, one in front, one in back, so that their leaps become pathetic small hops. That is all their lives amount to anyhow, and it is good for them to be able to see, in the mirror, their whole life-histories performed, in a sequence perhaps five minutes long, of upward movements which do not, really, get very far or achieve very much. Without the tires, the leaping father has a nuisance value which may rapidly transform itself into a serious threat. Ambition is the core of this problem (it may even be ambition for you, in which case you are in even greater danger than had been supposed), and the core may be removed by open-liver surgery (the liver being the home of the humours, as we know).
