  While observational evidence for the episodic nature of young stellar
outflows continues to mount, existing numerical and theoretical models of
molecular outflows assume they are formed by the interaction of a non-episodic
wind from a young stellar object with an ambient cloud. In this Letter we
estimate and discuss the effects of episodicity on the mass-velocity and
position-velocity relations observed in molecular outflows. We explain how many
recent observational results disagree with the predictions of non-episodic
outflow models, and we offer simple explanations for the discrepancies. In
particular, we discuss how an episodic stellar outflow can steepen the
power-law slope of the mass-velocity relation in a molecular outflow. And, we
illustrate how an episodic outflow can produce multiple "Hubble-wedges'' in the
position-velocity distribution of a molecular outflow. With a little more
information than we have now, it may be possible to use the "fossil record"
embedded in a molecular outflow's mass-velocity and position-velocity relations
to reconstruct the history of a young stellar object's mass ejection episodes.
