Query: Pulsar Recoil and Gravitational Radiation due to Asymmetrical Stellar
  Collapse and Explosion   New data imply that the average velocity of radio pulsars is large
\cite{hla93}. Under the assumption that these data imply that a pulsar is born
with an ``intrinsic'' kick, we investigate whether such kicks can be a
consequence of asymmetrical stellar collapse and explosion. We calculate the
gravitational wave (GW) signature of such asymmetries due to anisotropic
neutrino radiation and mass motions. We predict that any recoils imparted to
the neutron star at birth will result in a gravitational wave strain,
h$^{TT}_{zz}$, that does not go to zero with time. Hence, there may be
``memory'' \cite{bt87} in the gravitational waveform from a protoneutron star
that is correlated with its recoil and neutrino emissions.
