“A tiger's DNA is also a 'duplicate me' program but it contains an almost fantastically large digression as an essential part of the efficient execution of its fundamental message. That digression is a tiger, complete with fangs, claws, running muscles, stalking and pouncing instincts. The tiger's DNA says, 'Duplicate me by the round-about route of building a tiger first.' At the same time, antelope DNA says, 'Duplicate me by the round-about route of building an antelope first, complete with long legs and fast muscles, complete with timorous instincts and finely honed sense organs tuned to the danger from tigers.”

“DNA neither cares nor knows. DNA just is. And we dance to its music.”

“Time is the tiger that devours me, but I am that tiger.”

“The one certainty in tiger tracks is: follow them long enough and you will eventually arrive at a tiger, unless the tiger arrives at you first.”

“Different sorts of survival machine appear very varied on the outside and in their internal organs. An octopus is nothing like a mouse, and both are quite different from an oak tree. Yet in their fundamental chemistry they are rather uniform, and, in particular, the replicators that they bear, the genes, are basically the same kind of molecule in all of us—from bacteria to elephants. We are all survival machines for the same kind of replicator—molecules called DNA— but there are many different ways of making a living in the world, and the replicators have built a vast range of machines to exploit them. A monkey is a machine that preserves genes up trees, a fish is a machine that preserves genes in the water; there is even a small worm that preserves genes in German beer mats. DNA works in mysterious ways.”

“Dealing with jackasses on every front today. Good thing I have tiger blood and Adonis DNA. (Charlie Sheen Reference)”

“Are you afraid of the tigers? Do you hear them padding all round you on their fierce fine velvet feet? The speed of growth of tigers in the nightland is a thing which ought to be investigated some time by the competent authority. You start off with one, about the size of a mouse, and before you know where you are he’s twice the size of the Sumatra tiger which defeats all comers in that hemisphere. And then, before you can say Knife (not a very tactful thing to say in the circumstances anyhow), all his boy and girl friends are gathered round, your respectable quiet decorous docile night turns itself into a regular tiger-garden.”
