  The Crab Nebula has long been considered a standard candle in high energy
astrophysics, but in recent years this assumption has been strongly
contradicted in keV-GeV wavebands. In light of these developments, a search for
variability is being performed on the nebula at Very High Energies (VHE; E>300
GeV), the preliminary results of which are presented here. This initial study
is based on 10 years (2001-2011) of archival data from the Whipple 10 m
telescope. The data set was searched for evidence of variability on the
timescales of 1, 7, and 14 days. To date, no significant flaring activity has
been found, but simulations are in progress to determine the level of
variability that would be detected.
