  The newly discovered "Higgs" boson h^0, being lighter than the top quark t,
opens up new probes for flavor and mass generation. In the general two Higgs
doublet model, new ct, cc and tt Yukawa couplings could modify h^0 properties.
If t --> ch^0 occurs at the percent level, the observed ZZ^* and \gamma\gamma
signal events may have accompanying cbW activity coming from t\bar{t} feeddown.
We suggest that t --> ch^0 can be searched for via h^0 --> ZZ^*, \gamma\gamma,
WW^* and b\bar{b}, perhaps even \tau^+\tau^- modes in t\bar{t} events. Existing
data might be able to reveal some clues for t --> ch^0 signature, or push the
branching ratio B(t --> ch^0) down to below the percent level.
