  Recent measurements of the top quark forward-backward asymmetry at the
Tevatron could hint at new physics with an unexpected flavor structure. The
significance of such an abnormal flavor structure in alleviating the tension
between the various determinations of $|V_{ub}|$ via right-handed charge
currents is studied. In particular, we elaborate on how the associated new
flavor changing couplings naturally allow for the generation of anomalous
loop-induced right-handed charge currents which can simultaneously remove the
tension in the determinations of $|V_{ub}|$ and escape the tight indirect
bounds from $B \ra X_s \gamma$.
