  We show that when the unparticle sector is coupled to the Standard Model,
unparticle excitations can decay to Standard Model particles. This radically
modifies the signals of unparticle production. We present a method for the
calculation of the decay lifetimes of unparticles. In a particular model, we
show that depending on their lifetime, unparticles can manifest themselves
through monojets, delayed events or prompt decays.
