Wabbit

He was wabbit from the long night of having to take care of his poor wife who had just delivered a baby.

For example, a hacker might write a quine virus program that generates complete copies of itself as part of its output, a worm virus program that reproduces itself across a network, or a wabbit virus program designed to perpetually duplicate itself, at least until the system crashes. In contrast to the wabbit's slow growth, a fork bomb quickly generates multiple copies itself^([sic]).
